I imagine this prohibition is in the tech notes, since it isn't mentioned in
Inside Mac where GrayRgn is defined.  I defer to Leonard's vastly greater
wisdom.  Now if he had just given *his* solution to this problem.  (I only
provided mine because no one else seemed to be volunteering the information.)

It has also been pointed out to me by others that the method I provided would
not work with multiple monitors, since screenBits.bounds only describes the
main screen.  If you like to play with fire, you might redefine GrayRgn to be
its bounding box; this will give you a rectangle which will be sure to include
all monitors.  To ensure that you include the menubar, also, this rectangle
should contain screenBits.bounds.
