    Description

      Problem:

      • When closing a window its WindowedSystemManager is not removed from SystemManagerGlobals.topLevelSystemManagers.
      • When opening several Windows and closing them, all left-over WindowedSystemManagers are still included when
      • WindowedSystemManagers.dispatchEventToOtherSystemManagers() gets called. This results in grave performance degradation.

      Result:
      The application stops responding. if I do a process sample while the app is hanging (spinning wheel) I get the attached stack trace.
      In talking to the APE team, Eric Berdahl mentioned that this is a Flex problem.
