AH crashes when minimized with a combination of WinXP 64 and my 7800 vid card.
I've done a ton of upgrades... WinXP 64 and a 6800 didn't cause the crash, and WinXP with a 7800 don't cause a crash, only a WinXP 64 and 7800 combination.
I found out the above by swapping out vid cards and going with a dual boot system.
It isn't that big a deal really, unless some newbie with the above setup tries to view the HTC via the help selection on the clipboard.
