wine users - Jun 2009 - Unreal Tournament 3 Mouse Bug

Yeah, can't wait for the native client and anyway it was Steam free weekend
so I went ahead and downloaded Unreal Tournament 3, the game runs immaculately
and performs surprisingly well on my rather low-end 8400gs, but one problem: I
can't aim.
The mouse works fine in the menus but during actual play im unable to aim,the
mouse can move but only slightly, I put mouse sensitivity up to maximum but this
didnt help.
I entered the MouseWarpOverride=force registry key as said on the appdatabase
entrybut that didn't do anything, neither did using native dinput.dll.
I've searched at great length for a solution and can't find one, any
help would be greatly appreciated.

It is a known issue and there is no solution for it yet (see bug
http://bugs.winehq.org/show_bug.cgi?id=6971). We need changes in X and some
fixes in Wine. The next Xorg will contain Xinput2 and that will allow what we
need.
