VLC can't be shown if --qt-start-minimized have been used to launch it
When you start VLC using --qt-start-minimized argument, its GUI is hidden and should be set visible if the user click on the systray icon.
Clicking the systray cone icon does nothing except changing its contextual menu text (first entry change from show.. to hide interface)
Tested on Windows Vista, VLC 1.0.1 and latest NB (23 July 09) @see http://forum.videolan.org/viewtopic.php?f=14&t=62697
