Crashing when Alt Tabbing

[fohkure]

About 50% of the time I alt tab, EQ client crashes when I come back. My computer doesn't freeze or anything, i just get an error window that EQ has crashed. I can't even do anything with the error window, i have to go to the task manager and close the EQ windows (EQ and error window) from there.

I am running an AMD 64 dual core with only one core running, on windows Vista. Typically i do not have anything running in the back ground except for 1-3 tabs open on Google Chrome.

Any ideas what could be causing this? It's really aggravating when I alt tab over to look at a map or a quest and crash half the time when i go back to the EQ window. If i don't alt tab, EQ never crashes.

Thanks in advance!
