Has anyone has this error message:

Fatal error: Exception code=C0000005

This occurs every time I close my app down, which is an exe running on a novell network. I cannot find any information on this error anywhere, including the VFP help files, and MSDN.

The error appears on a MESSAGEBOX with an OK button, after I click on OK, the machine hangs and I have to reboot.

Has anyone come across this before? Does anyone have any information on it?
