--- Comment #5 from Mel winehq@the-eend.org 2008-05-16 07:55:00 --- I thought it might be a bug in Compiz, which is why I tested the ctrl-click behaviour in a game which *didn't* use wine. The fact that compiz affects wine's input-handling behaviour does indeed point to a bug in compiz. However the fact that compiz *doesn't* affect non-wine games points to a bug in wine. Wine should surely handle receiving input just as any other linux application does, no?
I've just tested the Dungeon Siege 2 demo, and it has the same ctrl-click problem (just so I know it's not only the one game).
Posted a message in the compiz-fusion forums (basically replicating this bug report so far). Maybe someone there can shine some light: http://forum.compiz-fusion.org/showthread.php?t=8365
