This pertains to WL bzr5882 but has been this way for > a year on my Win XP (32) SP3 installation.
I thought this covered by another bug report, but was advised to file as a new report.
When WL is running in Full screen mode, the mouse is disabled for any other application when I ALT-TAB out.
I can see the mouse pointer in the upper left corner of the Screen (Desktop), but it does not react to mouse movements.
WL is installed in D:\Games\Widelands_5882
I start WL with Widelands.exe in the above mentioned directory without passing any other parameters.
There is no config file in this directory at this point. The stdout.txt produced is attached here.
The file "C:\Dokumente und Einstellungen\Wolf\.widelands\config" contains the following:
_______________________________________________________________

I can confirm that this is happens also with Windows 7 (trunk r5868).
