I didn't played very much with DOEVENTS and AUTOYIELD, but from what I remember from some tests I did a few months ago and from the help, I would say that AUTOYIELD must be set to .F.

From the Help for AUTOYIELD = .F.:
"All pending Windows events are placed in a queue, and the events in the queue are processed when DOEVENTS is issued or a wait state occurs."

Hope I'm right,
