I hope this is not the wrong place to ask this. I am running a DOS program under the Windows XP Guest OS. The program works ok, but sometimes I need to press Ctrl+Break in order to debug it (I am the unlucky sap who has to maintain this legacy code). I am using a MacBook Pro. How can I get a keyboard equivalent of Ctrl+Break? In addition to struggling with this under Parallels Desktop, I'm having the same issue with it in Remote Desktop under native Mac OS; in this case I am many miles away from the PC running the DOS program, and the lack of Ctrl+Break is turning into a REAL problem.
