The code to deselect the first entry in the listbox simulates a left
button click on the first entry 10 pixels from the top of the listbox
and 10 pixels from the left with the ctrl key held down.  In order for
dBASE to know exactly where to simulate the left-click the form's metric
needs to be in pixels.
