>I know about the use of RETURN inside of WITH - ENDWITH; I am skeptical that this is your true cause. I have this code construct in many places and never had any crashes and my current application has been running in production for over 3 years (I have older ones that date back 10 years with no crashes reported). You said in your first post that this was occurring during pasting into an OCX control from the clipboard. How is this related to the RETURN within a WITH - ENDWITH? Is the crash occurring immediate on the copy-n-paste or when the user is trying to save or do something else? Where is the C5 originating from (what method). You could spend a lot of time changing all the WITH - ENDWITH coding to only find the problem is still present.

>I have found that many times during a copy-n-paste from other sources there can be many control codes embedded into the string being pasted. The fix was to first 'scrub' the string of invalid characters before pasting; i.e. ASCII codes 0-31 (except TAB, CR, and LF) and any codes above 132. This might be the true culprit.

The place where this crash is happening is within a very complex form. It seems to be happening when there are several (15) users in that particular form while about 50 more users working with our other software which involves updating same SQL Server tables.

There is long code in BarAdded event of the ActiveX which I believe is happening when this particular operation is done. In that code I see some returns inside the with thisform endwith block.

I can examine other methods in that form. Fixing that thing may be the simplest first step, but as I said, too many unknowns here.
