>I am building a form where the user moves objects around the form. The form has virtual columns and the object needs to re size to the column width on MouseUp. I have all this working. The problem comes when the user drags an object to the far right column and the mouse pointer is off the screen when they let go of the button. VFP does not detect the MouseUp if the mouse pointer is not over the VFP _screen.

I figured out a way to do it.

I set a flag property in the form from the MouseMove event of the object I am moving. Then I call the re-size procedure from the MouseMove of the Form if the flag is still true. Thus, when the user releases the mouse button off of the screen, as soon as the mouse passes back over the screen the re-size proc gets called. I left enough margin around the form so the screen does get hit before the mouse passes over any object.
