Control Break not working??

[Harwyn Berens]

	Running 4.05 on Windows XP.  When we're at the "Run A User Menu" screen 
and hit Control Break nothing happens.  We have to choose a high-lighted 
menu which puts us at that menu and then hit "X" to return to the main 
menu.  When at all (I'm not sure if I checked every one, but close) the 
other "initial" screens under Creation Operations or Runtime Operations, 
hitting Control Break returns us to the main menu.
	This isn't impossible to deal with...just an irritant.  Any suggestions as 
to how we can fix this?
