Piece o' cake- Set the MBarHeight to Zero Pixels. You can probably find
the exact name of the System Global in the back of IM or a debugger manual.
If you want to see an example of it, investigate 'Macintosh Programming
Primer', Vol.1.
Just make sure to get it's original height and restore it once you've had
your fun with it.
