Problems with OnMouseMove

[Sychotix]

When using OnMouseMove, I am trying to get the location of the mouse. Of course, there is an x and a y that is returned with this function.

With the simple game I am making, I am trying to do "Player.Left := X; Player.Top := Y;" yet the green box (the object im manipulating) wont move at all unless i move my mouse over it... which at that point it will go over to the top left side of the form.

Is this some problem with Windows7/Vista x64 or Aero? I only have these two OS's and they both have the same exact problem.

EDIT: problem solved.
