Meaning something went wild and changed some part of memory that it had no business messing with. It could *conceivably* be bad RAM chips, but most likely it is a software problem. Try to narrow down the problem--does it only happen with a few specific applications? Try removing any third-party desk accessories or setup files and see if that has any effect; if it does, put them back one at a time and maybe you can determine which one is misbehaving. "Flaky" problems like this are hard to pinpoint sometimes, because just removing something could make the problem go away "by accident", just by changing the relative positions of things in memory. -- David A.
