Alright, I just got mac os X Leopard, and ever since, at least every session, i get this blue screen, out of nowhere without any warning, and it goes away after a second or two, and then shows my desktop, just like it would be after i'd log in, and all the programs would be closed. It's very frustrating, I'm just talking on MSN, or on safari, and out of nowhere, I see a blue screen for a second, then i have to restart every program i had running. I checked the console, and there's nothing obvious there. I also can't be sure if this ever happened on tiger, but i just know it happens a lot in leopard. This blue screen also hangs a bit on startup, but it's not that big a problem. Could anyone tell me what this problem is even called, i don't even know how to google this problem. I really want to get this fixed, before i start doing serious school work, and i'd have to start half way through because of this problem. Thank you!!
