Next time you get the NT 'blue screen of death' note the last value in the bottom right column. It's name of the driver that was being used when your abend occurred. You wouldn't have any Classes, cursors or controls on any forms that came from a different drive or partition? I've seen the same message when the latter has occurred.

>>>Everything looks OK except one very elaborate VFP5 form which gives me an 'Access Denied' error if I run it from the command box. It runs OK if compiled, and (very oddly) it will run OK when called from 2 forms but not when called from 2 others. In the latter cases, I get an 'access denied' message from one form and an 'out of memory' error from the other.
