TightVNC 2.0 Beta 4

TightVNC 是一款加強版的 VNC 遠端控制軟體，主要解決透過網路操作另一台電腦的需求。它讓您用本地端的滑鼠與鍵盤，連線到指定 IP 的遠端機器，並可隱藏本地游標，避免雙游標干擾。其高效率資料傳輸與 JPG 壓縮，讓中低速網路下也能維持流暢的畫面更新；同時支援「完全控制」與「僅檢視」兩種權限密碼，提升安全性。這套開源工具長期維護，更新頻率穩定，在同類工具中屬於老牌且口碑不錯的選擇，但人氣不如部分商業或整合型軟體。

它適合需要輕量、免安裝的遠端桌面方案的使用者，例如臨時協助親友排除電腦問題，或管理家中或辦公室的數台機器。與 TeamViewer 或 AnyDesk 等商業軟體相比，TightVNC 沒有中繼伺服器，需自行設定網路與防火牆，但換來的是開源與可自訂性。若兩端都安裝 TightVNC，可啟用加強功能；若對方使用其他 VNC Server，也能維持基本連線。目前僅提供英文介面，Windows 平台可下載，使用前需留意語系與設定門檻。

TightVNC 是一套加強版的 VNC (Virtual Network Computing) 軟體，使您能透過網路隨時隨地的控制遠端電腦。

• 可經由 VNC 連線到某一IP位址的遠端電腦，並利用本地端的滑鼠及鍵盤來控制該電腦。
• VNC 控制過程，可隱藏本地端滑鼠游標，免去了出現兩個游標的困擾。
• 高效率的資料傳輸，使您在中低速的網路下也能有良好的畫面更新速度。
• 遠端影像JPG 壓縮功能，有助於您更快速地傳遞影像。
• 遠端的網路控制功能的加強，有助於您更順暢的瀏覽網路。
• 可依權限設定「完全控制遠端」或是「只顯示遠端畫面，而無法操控」的密碼，藉此增加安全性。
• 可對 UNIX 自動啟動SSL功能。
• 若有一方的Server端是使用其他 VNC Server ， TightVNC 仍可支援其基本功能；如兩邊的Server端皆安裝TightVNC，則可享用加強版功能。

* Installer for Windows: Fixed a bug with uninstaller not removing TightVNC entries from Add/Remove Programs list. Also, new installer should remove invalid entries left by previous Beta versions.
* Installer for Windows: Trying to recover registry entries created with wrong permissions by previous Beta versions. Correct permissions to the service-mode configuration should give access only to SYSTEM and to the Administrators group.
* Server for Windows: Fixed a bug with not simulating AltGr (Alt and Ctrl) to produce characters that require AltGr to be entered correctly in current keyboard layout.
* Server for Windows: Fixed cursor shape updates that were encoded and sent incorrectly if the cursor width was not a multiple of 16. That led to disconnects due to broken protocol synchronization.
* Server for Windows: Control interface erroneously tried to read configuration from the registry after it was already given that configuration by the service. That could cause IP access control rules to disappear from the configuration under certain circumstances.
* Server for Windows: Registry entries could be created with wrong permissions while writing configuration or installing initial service-mode passwords.
* Server for Windows: Solved the problem of not shutting down the control interface if the tray menu was open at the moment of shutdown.
* Server for Windows: More logging has been added to trace RFB initialization sequence for client connections.
* Server for Windows: Fixed a problem with sending framebuffer updates for screen areas beyond the requested region.
* Viewer for Windows: New version fixes problems with sending key combinations like Ctrl+A, Ctrl+[ or Ctrl+Shift+^ that should produce control characters with ASCII codes below 32.
* Viewer for Windows: Various other key combinations with Ctrl and AltGr have been fixed.
* Viewer for Windows: Recovered CapsLock functionality that was broken in previous Beta version.
* Viewer for Windows: Key codes have been corrected for a number of keys: F1, F2, F3, F4, "=".
* Viewer for Windows: New viewer will reset keyboard modifiers to their actual state on restoring keyboard focus. After leaving the viewer window with Alt+Tab and returning to the viewer again, Alt could get "stuck" and one would need to press Alt once again to restore correct keyboard handling.
* Viewer for Windows: Win key presses will not be propagated to the server any more. Otherwise, combinations like Win+R would have both local effect (e.g. open the "Run" prompt) and also open the Start menu remotely.
* Viewer for Windows: Special ScrollLock functionality has been restored. When ScrollLock is on, the viewer will send Meta on pressing Alt. This may be handy when working on Unix servers.
* Viewer for Windows: Fixed a problem with adjusting the listening port number using arrow buttons near the text field. It could add thousands separator and produce invalid numbers in the text field.
