wine users - Aug 2009 - WINE and NVIDIA issues - scrolling away from fullscreen

Hi everybody :)
I seem to have a problem with my WINE running fullscreen applications, such as
games. When I start, say, a fullscreen game, it does start in fullscreen, but if
I move my mouse to the right or bottom edge of the screen, the game screen
"scrolls away", and I'm shown my desktop (at a lower resolution).
When I pull my mouse/touchpad back to the left or upper edge, the screen
returns.
I'd love to post screenshots of this, but those show nothing useful :(
(which leads me to a suspicion there might me something wrong with my display
configuration - but this is only a suspicion.)

It happens regardless of Compiz or any other window manager, and regardless of
the "Graphics" settings in winecfg. This is only the case with WINE;
I've tried some native fullscreen games, which work flawlessly.
This is really annoying, as it renders most of the games unplayable.

I have an NVIDIA GeForce 9600M GT graphics card, and am running the 64-bit Arch
Linux. Here's my xorg.conf (http://pastebin.com/m5136eb18) and my Xorg.0.log
(http://pastebin.com/m7b37c665).

I'd be very grateful if someone could help me with this. Thanks!

There are some Wine mouse issues which require fixes in Xorg and Wine before
they can be fixed.

In this case I think you don't have a 32-bit xrandr library or your Wine
hasn't been compiled with xrandr support. When xrandr is around Wine
switches the resolution of your desktop to the game resolution without xrandr
(we then fall back to xf86 vidmode) the resolution is still changed to the game
resolution but the desktop size doesn't change.

would a 32-bit xrandr library work on a 64-bit system?
