Unfortunately, Windows 7 is still in beta and is not a commercially available operating system. For that reason, we cannot diagnose bugs when the game is running in a beta environment.

It is normal for there to be two processes running for our games, so that's not part of the problem. When we've seen hangs on quit in Vista, it's usually a problem with audio drivers or low-level audio routines, which could also be likely in Windows 7, which is based on Vista.

Using Task Manager to end the game will not normally cause any damage to the savegame files in this situation.
