There is a bug in VFP7 where mouse input does not work in a top-level form if the form is scrollable, and a toolbar is docked to the top of the form.

We fixed this in VFP8.

Is your form top-level, and does it have scrollbars?

>Hi all -- I've encountered a form/toolbar interaction I've never seen before. I have a modeless form and a tool bar. The toolbar is tied to the form by an object reference:
>thisForm.oToolbar = oApp.DoToolbar( this.cToolbar )
>
>If the toolbar is docked, the form will not accept any input.
