Well, sorta. I was playing online last night, just spawned and got on a heli to carry me to the action. We gained altitude and were heading out when the screen just went black.
At first, despite a 65ms ping, I thought I'd just lost the connex, got bumped off the server. Then, I get one of those MS error popup windows "Sorry, Arma 2 had to close. Send Error report to Microsoft?'
I haven't played CO that much yet but 1st time its even hiccuped on me. And this is apparently something 'serious' for XP to have shut it down yet I have no idea what might have caused it.
