Finding the coordinates of a form..

I have a form that opens at "Center Screen." I'd like to find out what the coordinates of the top and left corners are so that I can place a form on top of that form at a "relative" location.

If I look at "form.left" it contains a value of -15 ... This doesn't seem reasonable to me. The CurrentLeft doesn't seem to do too much for me, either.

Anyone have any ideas?

Thanks..
