>Trouble is, I have no idea whom to tell at Microsoft.

By posting this here, you've told them. At least two people from Microsoft's Fox Development Team periodically check the U.T. for bug reports, as well as to offer a few helpful hints.

Specifically, when I posted info about a C0...5 instance I got, Randy Brown contacted me a day or two later to ask me for code samples and more details.

The Fox Team is working on solving the C0...05 errors, but be aware that (like Barbara and others before her have said) it's a class of errors very much like old Windows 3.x GPF's, not a single error for Microsoft to "find and fix."

HTH,
