Dear pfGuys,

I'm having a strange bug in my performer program.
After drawing the first frame, my pfPipeWindow just disappears. Here are a few remarks about when it happens :
1/ This only happens in bi-process mode (typically PFMP_APPCULL_DRAW)
2/ This does not happen in monoprocess (PFMP_APPCULLDRAW) mode
3/ My draw process does not die and continue to loop
4/ The function pfPipeWindow::isOpen() returns yes during all the draw process
5/ I can see in a short flash that the first frame is almost drawn completely, and then the window disappears...

I would like to trace in debug mode what is the data member of my pfPipeWindow (or else) which changes its state and make it disappear from the display. Do you know what can make a window disappear without killing it ?

Has anyone ever met such a mysterious behaviour ?

I have no code example since I think it is its complexity which make it bug through a wrong allocation or so. I'm just trying to find the criteria to trace where does the bug happen...

Thanks for your help!

Mike
