Comment 9 for bug 811864

The observed behaviour is related to the window manager. First it does not support the tray area. Second the virtual desktop seems to be implemented by only minimizing the windows, which are not on the active desktop.
wxWidgets 2.8 does not offer an option to get an information about the availability of the tray area. So deactivate the tray icon on *nix, this should restore the old behaviour. -> therefore setting to incomplete.
If there are more information set the status to new again.
