>Back in the days before SP3 when I was getting C5s, it was apparently due to issuing CLEAR ALL with dangling references, or maybe just dangling references alone when closing forms/apps. Setting all possible object property references to .NULL. seemed to resolve it - at least I never have seen the C5s since then.

Yeah on FoxForum Steven Black wrote a brief article
with some code snippets that automatically NULL
out object references.

It was pretty slick. Didn't fix *my* problem, but
pretty slick none the less :-)
