Message-ID: <32330@cup.portal.com> Date: 1 Aug 90 07:40:57 GMT References: <1990Jul31.173834.23808@Octopus.COM> Organization: The Portal System (TM) Lines: 17 As far as I know, CodeView doesn't run in a window. If you've ever been debugging a PM program and accidently tried to switch screen groups at the wrong time, you found out why. PM has a single system message queue and if one process is processing a message, others processes must wait -- in fact, PM as a whole must wait. That means that you can't switch back and forth between WINDOWS when debugging, though you can switch SCREEN GROUPS. Bill --- William B.
