FlashFXP 5.4.0 build 3970

- Updated SecureBlackBox Library, this update addresses an issue that caused errors importing ECDSA keys and using them with public key authentication.
- Added support for chacha20-poly1305@openssh.com
- Added ctrl+F3 shortcut to find previous after using F3 to find next.
- Added advanced feature to display and delete ssh host keys using a raw command macro /dialog ssh_host_keys
- Fixed: In some cases FlashFXP incorrectly handled remote files and folders named "/" and the result was unexpected and unpredictable.

- Fixed minor issue where pressing Ctrl+V while renaming would trigger the view file feature.
- Updated language translations.

- Fixed when Queuing/Transferring via the Server File Search dialog invalid characters in the source file-name were not replaced in the target file-name before attempting to download.
- Fixed the Queue Selected and Transfer Selected buttons were only functional when the browser pane was activated.
- When moving a file/folder via drag/drop in the local browser the "move file/folder" confirmation prompt is now correctly shown.
- Added new global remote edit option located in the Preferences dialog under the "View/Edit file" section named "Create a backup copy of file original file on upload". On the first edit of a file a backup is created named ., the timestamp is the current modified date/time of the file.
- Added new per-file-association option located in the File Associations dialog named "Create a backup copy of file original file on upload".
- Changed the behavior of the Server File Search dialog, you can now minimize this dialog.
- Added new /dialog custom command to open dialogs used within FlashFXP, this allows the user to bind a custom shortcut to open these dialogs, more information can be found in the help file.
- Fixed remote browser caching issue when connected to two remote servers (one in each browser pane) when performing a Server File Search on one side while navigating folders on the opposite remote browser caused the folders to not be cached.
- Fixed remote browser caching issue where a failed directory listing or aborting the list operation would clear the cache for all child folders.
- Fixed issue where FlashFXP would sometimes fail to refresh/update the directory content of shared folders when running under a VirtualBox VM, these drives are virtual mapped drives and certain Windows Network API's cannot be called on them otherwise the function calls fail

* Fixed crash running scheduled tasks that perform site to site transfers, there was an error that referenced an object that didn't exist resulting in an access violation.
* When retrieving a directory listing over the SFTP protocol the bytes received is now shown in the status-bar panel.
* Added command tokens %n to reference the name part of a file without extension and %e to reference the extension (.ext)
* Added /set @var@ ("title","text") token modifier to allow the user to bring up the folder select dialog and store the result in @var@

- Fixed: Issue with creating a new custom command if no custom commands exist.
- Fixed: Custom Command /deselect when using a modifier i.e. /deselect * :age+1d
- Fixed: QueueAs/TransferAs (previous build didn't resolve the problem).
- Fixed: Several issues with the queue item editor.
- Added new raw command; /edit "" to open the file for editing.
- Added new raw command; /view "" to open the file for viewing.
- Added new advanced setting via raw command; /set app.os.theme <0|1> set to 0 to turn off theming on list-view and tree-views, 1 to re-enable it. If you're using a dark color scheme it may be more desirable to have themes turned off.
- Added new advanced setting via raw command; /set app.queue.parent <0|1> typically the parent folder entry in the file list cannot be queued/transferred, this override re-enables this behavior allowing the parent directory entry to act as "all items in folder"
- Fixed issue editing UTF-8 files via the internal editor.
- Fixed issue with certain raw commands not executing correctly when run via the transfer queue.
- Changed the way the delete confirmation prompt is shown in the local browser when enabled, if the OS is configured to show a confirmation prompt then that prompt is shown otherwise we display our own confirmation prompt.
- Added new experimental raw command; /copyfile "" "" this command works both locally and remotely, if the server protocol doesn't support a direct copy then the file will be downloaded locally and then uploaded to create the copy.

- Changed: Reworked the Site Manager dialog, site profile settings have been Reworked so that they are now consistent across all connection types, FTP, SFTP, FTPS. Each connection type now has its own tab for connection specific settings.
- Added: The ability to set a custom Sftp Server via the Site Manager > SFTP Tab.
- Fixed: Corrected issue in an internal UNCPath function that could incorrectly handle serverpath paths.
- Fixed: Custom Commands > Using the /busybox command followed by the /confirm command could cause FlashFXP to freeze up.
- Changed: Custom Commands > The /busybox dialog now hides while another dialog window is being shown.
- Fixed: SFTP > When the SSH client is unable to automatically launch the SftpServer several alternatives locations are tried automatically, the method for starting these alternatives was flawed and in some cases resulted in a failure to start the SftpServer.
- Fixed: Resolved an issue with an internal function that was used to determine if multiple items were selected, this caused some basic functionality failure under some conditions.
- Fixed: Resolved an issue with the queue list right-click menu and right-click menu shortcuts not always working as intended.
- Changed: A previous fix for resolving an issue with incorrect file icons introduced some undesired lag when scrolling the file listing, the fix has been reworked to eliminate this lag.
- Changed: By default FlashFXP uses the Windows operating system defined fonts, this change was saved even if the user did not change the font, as a result when the system font changed FlashFXP continued to use the old font.
- Changed: The OpenSSL dlls are now statically linked to the FlashFXP.exe, as a result they are now required to use FlashFXP. This was done to resolve issues where in some rare situations FlashFXP was using OpenSSL dlls from another application, which in some cases was an older version of OpenSSL.
- Changed: Custom Commands > @var@ variables can now be used within token modifiers.
- Fixed: Using QueueAs/TransferAs did not use the new filename in some situations.

- Fixed: Text selection in the status console window failed to copy the text to the clipboard in some specific situations.
- Fixed: Loading a queue file that referenced sites that no longer existed in the site manager / quick connect could result in a crash.
- Changed: On the remote folder select dialog the path input control was changed from a edit to a drop-down box and is now populated with previously selected paths during the current site session.
- Changed: The remote folder select dialog now remembers its size/position.
- Changed: The site select/add site dialog now remembers its size/position.
- Fixed: In some cases a remote move operation would fail when performing the operation via the right-click "Move" command.

# Fixed:
- Loading and executing a saved queue that references sites by ID (i.e Auto saved queues) that no longer exist in the Site Manager could under some conditions cause FlashFXP to get stuck in an infinite loop and lock up.
- Under a rare condition the Queue List window might cache the wrong site name and the remark column would display the wrong site name. This did not effect functionality and was only a visual issue.
- Local browser drag operations incorrectly passed a UTF-8 encoded path-name when calling a windows API when it should of used Unicode path-name, this caused some drag/drop operations to fail.
- After the desktop color depth changes sometimes FlashFXP would incorrectly render the toolbar buttons with an opaque background.
- If FlashFXP is left minimized while the local browser is displaying the content of a network drive/location and this location becomes unavailable it could cause FlashFXP to freeze for an unusually long time or lockup when restoring the window.
- Synchronized browsing issue where the remote synchronized root path was not correctly defined under some conditions.
- Scheduled tasks > If the task failed as a result of being unable to resolve the server host name this reason was not clearly indicated.
- Internal file read-only check on data files was incorrectly passing Unicode file-names to ANSI version of APIs.
- Eliminated multiple RedrawWindow() API calls after unlocking the window canvas for drawing due to erroneous DrawLockLevel evaluation.
- Indirect site to site transfers were experiencing a problem that caused the UI to appear frozen between the download and upload operations while waiting for the file to become ready.
- In some cases FlashFXP was unnecessary reloading the FlashFXP data files from disk.
- Remote editing, auto uploading on save could in some specific cases try to upload even when another operation is in progress resulting in a failed upload.
- After a download transfer failure attempting to re-transfer the file could incorrectly result in the file being skipped.
# Changed:
- Clipboard monitor now uses a more reliable monitoring method on Windows Vista and up.

- During the build process of the previous release something went wrong when linking the units and the wrong units were linked. The linked units had the wrong compiler flags and as a result some basic features malfunctioned.

- This update addresses an issue where FlashFXP may inadvertently revert back to the trial edition.

- Changes made in our previous release have revealed an uninitialized buffer used to store error messages from OpenSSL. This can lead to unexpected errors within FlashFXP.

- Updated: OpenSSL 1.0.2a
- Added: new option in Preferences dialog under General > Options > Use single color application icon. When checked, the application icon will always be green, rather then changing colors based on the current program state. (red = offline, orange = connecting, blue = connected, transferring = green)
- Fixed: The session console window wasn't displaying lines with length of 1.
- Change: Improved file handling when downloading a single set of files using multiple parallel copies of FlashFXP.
