Does anyone know the details of why debuggers cannot get access to Presentation manager programs except in a full screen group. (They cannot run under a window in the same screen group as the program they are debugging) I hear that it is something about the message queueing. Any better info.? Is this going to be fixed in 2.0? (Another rumor) -Erik Freed ucbvax!pixar!freed

This is being fixed for 2.0. Alistair Banks OS/2 Group Microsoft
