Remember: ActiveX Controls are essentially mini Windows programs contained in their own (borderless) window. VFP creates a hole in it's own form-window where that ActiveX is then peeking through. For the user there is no visual difference, but programmatically it's a foreign module. With making it invisible, VFP just closes that hole in it's window, and then reopens it, which then forces the ActiveX module to use that hole...

Many thanks Christof
I hadn't but I have now and it works - quite bizarre. Do you have any kind of explanation?
