You may be getting glitches on your power lines (these can be REALLY confusing), so it might happen only at your home. It can be hard to diagnose unless lights or other equipment show changes (like dimming or brightening). It could be a PD or commercial utility leaving "time bombs" unintentionally. It may be an interaction of two incorrect programs (for example, one write to location 0, the other reads it and assumes it's 0). What version of 2.0 are you running? Does it happen if you run 1.3? (You should have 2.02 (version 36.207)). There was a WB disk for 2.02, did you update your system using it? The sort of thing you mention is a theoretical possibility, but that sort of error is quite unlikely assuming you did swap motherboard/disk/PS. (You did swap those, if I read your message right.) >My Commodore dealer is stumped because everyone he calls at Commodore >says that they havent heard a thing about this. I think they are >lying.

I certainly haven't heard anything like this, but then again I'm a software engineer, not hardware, let alone PA or Service.
