Wow; this message took several days to filter through! In the meantime what transpired I found that during the statusbox display, I used a 'yieldprocess' which was meant to be similar to processmessages, but it was not, so the message could not get through. Cheers, Alistair+ AG> MsgReceiver I define in the application as mainform.handle or application.handle AG> (tried both) and when the cancelbtnclk, it is not sending the message to the AG> application. Any ideas?
