Had this happen twice, on a huge map, with three players. (Also running WinXP, 32-bit, and yes, I'm getting a new computer, soon.) Double-clicked on a pack drake, and got a BSoD. Did it again; same thing. Third time around was strange: didn't get a CTD, but after the popup screen of the pack drake, the main map was largely black, with a few white bursts of light.
