   We have a Motif application with a pipe window that we
want to open and close multiple times. The pfPipeWindow
opens correctly the first time and then appears to close
ok. The next time we attempt to open the pipe window the
process hangs inside the call to pfOpenPWin.

   I have tried multiple solutions like remapping the widget,
reassigning the gl context, etc with no luck. Does anyone
know what processing is needed with the pfOpenPWin to undo the
pfClosePWin?

   We are running openGL, Performer 2.0, and Irix 5.3 on a
Indigo2 High Impact. The 'drawable' part of the pipe window
is set to a widget created by GLwCreateMDrawingArea. Run
as a single process, we do not fork Motif. Call stack included
at bottom.

    Any help is appreciated. Thanks.
