I have the following problem. Maya loads okay. I create an object say a poly cube. I try to Assign new material. Maya crashes and exits. There's nothing written in the log file. The problem occured when I had a low CMOS battery, but surely that wouldn't cause the problem would it? I'm using Maya 5.0 under XP. The problem also occurs in 4.5 so I assume it's not a software problem. Sorry I can't give more info, but that's all I have.
