Whats going on when vfp crashes with the above error message (seen when you look at the details after a "vfp has performed an illegal operation" message)

I can run a routine once or twice with no problem, then vfp unceremoniously bombs out. Even a reboot doesn't prevent it.

The debug just confuses the issue. If I stop the code just before the bomb goes off, It doesn't! Even if I immediately resume. But if I remove the breakpoint, it will fail on either the first or second subsequent pass.

Is this in any way associated with the C0000005 problem? - which I've also had with the same form once or twice in recent days despite having completely de/reinstalled vfp with sp3 a couple of months back.
