It's a bug in VFP8SP1. I don't see it in VFP7SP1. To work around this bug, set following properties

MinButton = .F.
MaxButton = .F.

>Hi All
>Using HalfHeightCaption = .T. and COntrolBox = .F. in a form i noticed that pressing on the title where the control box normally is displayed (near the right end of the title) is ossible to minimize and maximize the form.
>Infact for a piece of a moment pressing over a "hidden" button i see the button.

>Below the example code.
