Q44418: Switching Out of PM Application Hangs System under Codeview
Article: Q44418 Product(s): See article Version(s): 2.20 Operating System(s): OS/2 Keyword(s): ENDUSER | | mspl13_basic Last Modified: 16-MAY-1989 Question: I am using CodeView to debug my Presentation Manager (PM) application. Why does my machine sometimes hang when I use CTRL+ESC to switch to the OS/2 program selector? Response: Presentation Manager applications require the use of the Presentation Manager shell. To debug PM applications, CodeView must put hooks into the Presentation Manager before the PM application is executed. This process works properly while inside CodeView, but if you try to switch back to the program selector, PM is in an unknown execution state. Therefore, to switch out of CodeView while debugging a PM application, you must first restart or end the program inside CodeView. This tells CodeView to restore the Presentation Manager to its original condition.
