System version:
Win7, build 7000, version 6.1.7000 beta

Bug:
After clicking on quit, VF minimizes, however stays open. Problem is it is not clickable anymore, nor closeable. Moving mouse on the window hides cursor(window overlapping cursor). Closing it via (right click dock, close window) doesn't work. Had to end progress via task manager.

Note:
I found 2 Virtual Families.exe running. Using 250 kb to 500 kb memory AFTER the problems above.

Addtional testing:
Only happens when I play the game for like 30 minutes or more.

PSR report:
Unable to post report since I don't want it running for 30 min.


EVEN MORE DETAILS:
VF is pinned to dock.

Fine print:
I use dock as a term for superbar, for non geeks that's taskbar in windows 7.
