If you are using a older model PC/XT you may experience problems with the 
Shift-(key) Commands, try both set's of arrows (if you have 2) and toggle
the NUM LOCK to find out which combination will work with your keyboard.

If the program seems to hang at the copyright then SYNC probably didn't run
successfully - Type SYNC from the CustomMenu directory.

When you exit CustomMenu via ALT-X and you can not type anything but spaces 
at the DOS prompt; press ALT-SPACE and the problem will clear.  (This one's
got me?)
