So am I. As you, I could NOT reproduce on a simple form.

My **guess** is that I use WITH/ENDWITH through the whole code in the erroring form and possibly something gets a little confused as concerns the OLE object itself.
The DISable is early in execution and it worked OK. Never did try to see if it would fail next time. I think I'll do that tomorrow (I put the same code in both places, so I'll NOP the DISable code and go back to the original to see.

cheers

works from command window or errors out?
