>Alan,
>You are experiencing a bug that has existed since VFP5 and is one of the reasons that I jumped into this thread. I was hoping that you might have found a solution. The specific bug that I think you are experiencing is that if the user clicks on a part of the form that cannot getfocus, the lostfocus of the combobox is not fired.

Alan,
If that's acceptable for you, you might mimic combo with a txtbox+commandbutton + a grid showing on another form (other form would be with no title and borders showing if it was combo's dropdown). Then clicking on form would invoke grid form's deactivate.
