[Wine] Mouse trouble on dual screens.

[eyyYo]

Hello!
I have two screens for my computer, running at 1280x1024 (primary screen) and 1024x768 (secondary screen). When I play Day of Defeat: Source (running at 1024x768), the mouse cursor sometimes goes out to my secondary screen (when i move the mouse fast), causing the game to freeze for about 6 seconds, which is very anoying. This happens if I play the game at 1280x1024 too.
Is there a solution to this, that anyone knows of? Thanks in advance :)
