I recently have some weird problems and found wined3d.dll causes these issues.
For example, when I launch MSN Messenger, it crashes after loging into the system and when it shows up "today" pop-up window.
In the task bar, I see "wined3d_CapsWindow" showing up.
Same thing happend when I boot up with bootcamp.
Due to some weird reason, I had to re-activate my windows xp installation in the bootcamp, so I clicked a button to launch "Activating Window". However, the activation process crashes soon after and I also could see "wined3d_CapsWindow" in the task bar.
I simply removed "wined3d.dll" from C:\windows\system32 and reboot windows and everything worked fine at this time. MSN Messenger is working correctly without crash, and also bootcamp activation process went smoothly without problem.
So, I suspect wined3d.dll somehow conflicts with some other processes. I don't know which one it is, though.
