I've read through the thread and haven't found the answer to this.

My game freezes every time I try to close it. I am running the game on windows vista. I have no problems with graphics or sound and the game doesn't really 'stutter' or have problems loading up. Its just when I try and close the game. After reading this I thought it might be because I was pausing the game before closing, but I've just tried closing it without pausing it and I get the same thing.

I get no error message but the game freezes. I can access other windows such as messenger and I.E/ Firefox. It doesn't seem to matter what I use. It also happens if there are no other windows open. At that point I have to force the game to close using the Ctrl, Alt, Delete combination and get the 'This program is not responding message.
