Movable but non-resizable form

Hi,

First of all, thank you for this easy to use programming tools!

Is it possible to create a form that is movable but non-resizable?
If I use boarder_small or boarder_normal, the form can be move by draging the caption bar of the from, but the form is also resizable by draging the boarder. If I use boarder_hide, there is no boarder to drag, hence it is no-resizable, but in this case, the form does not have caption bar so it cannot be move by mouse drag.

Thanks!
