If I turn event tracing on I see that the mouseover() event fires on all controls BUT when I press the mouse button the click() event of the form fires instead of the individual controls event.

Can you test on a different computer with a different mouse/mouse driver? Just to eliminate any chance it's hardware/driver related.

It sounds like some part of the mouse operation isn't completing or an event isn't being cleared, and that's affecting the called form. I believe there's a mouse equivalent of CLEAR TYPEAHEAD but I can't find it in a quick search. It may be worth a try.

Another thing that has tripped me up from time to time is putting test code in various events/methods and neglecting to include DODEFAULT(), or inadvertently causing it not to be fired. If you have related events like MouseDown/MouseMove/MouseUp this might cause weird effects.

A SWAG, since you're using ActiveXs have you experimented with AutoYield?

Is LockScreen being toggled anywhere? Any ON KEY LABELs in effect?

Is there any unique code being fired by the calling form before it loses focus? Anything weird in there?
