[Wine] wine freezes entire System

[snejjj]

hi there,

I suppose, it's not an actual WINE problem, but I hope, you can at least tell me, where to get help.

I'm running "Lineage 2" with WINE 1.3.10 on Kubuntu 10.10 with proprietary ATI graphics-driver. 
after a (seemingly) random period of time, the entire system freezes. the only thing possible is moving the mouse-cursor, which doesn't change it's style anymore, when I move it out of the game-window.
I then have to hard-reboot my system, as nothing responds anymore.

I have no idea what causes the freeze, and since the entire system freezes, there's no way I can obtain a debugging-log, or is there?

greetings,
snejjj
