>I'm confused. Is a C00000FD error is the same thing as a C0000005 error? Is any C00000XX error the same thing as the infamous C-5 error?

Not exactly. C0000005 is an access violation, meaning that VFP was trying to get to memory that doesn't belong to it. C00000FD is a stack overflow. The causes for either one can be very different.

But for all intents and purposes the end result is the same: VFP crashes.
