+ was using the coord's based on the position on the screen.
+ That would work fine but it's a bit tougher to calculate the new
+ location (Take the mouse x, subtract the
+ form's left add the difference between where you clicked
+ ititially and the left of the control).

If you assume that the form won't move while dragging a control, then you
don't need the form top and left. Calculate the diffs relative to the
screen.
