> to prevent loss of time and user's focus a fresh instance of PeaZip is started in the last directory while the old instance is handled in background
- Added PanelIntro, usually not visible due to the speed of a normal startup
* if startup of the program is slowed for any reason user is informed about loading progress (0 inital form status 1 configuration and theming files loaded 2 input parameters parsed and executed)
