>I also am getting intermittent C5 errors on an app I just installed...hard to get a handle on it. I'm surely not "comfortable" w/it! Seems to happen when one form is closing or when the app is shutting down. SP3 is installed in all cases. I'll let you know more if I discover anything...J

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.
