I think it's a memory leak, but with no obvious cause that I can see; I've crashed whilst under intense load (at mass Scalis, see Europa boards) but also just quietly mining in Despise. I also don't get the slow down that I got from Corgul's explosions say, it's just an instant crash back to desktop. I'm on XP 32 Bit, so I don't believe it's OS specific either...
