Summary0027176: DragDrop faults.
Description When performing a drag and drop operation starting from lets say
form1 and while hovering over form2, if you perform a to
make sure the whole form is visible in dragover operation, it generates
a nil pointer fault in the Drag unit.
 This is ported code and works fine in delphi.

 A drag operation, once started from lets say form1 is not suppose to
be interrupted or nullified while it's doing a drag over other forms,
paint boxes, ect, until the user releases the mouse.
Steps To Reproduce
 IN my case, I start a drag from a Teditbox and when I drag over a
TpainBox in another form and do a form.Show, in case it's not the one
sitting in front, it generates this problem.

 I guess changing the form that is in front maybe the issue while dragging.
