The previous responses to this may have done the trick but if you're talking
about Performer PipeWindows ( using OpenGL ) then I've seen exactly this
problem and all that was needed was a missing call to pfpipewindow::addChan for
both pipewins and channels. The bones of the code would be ( detail ommitted ):

foreach window
{
  XtAppCreateShell
  visual = pfChooseFBConfigData
  make a motif drawing area and context
  make a pfPipeWindow
  pfPipeWindow::setWSDrawable and setGLCxt to that of the motif area
  pfpipewindow::addChan
}

If you have the problem I saw then you would have all this except the addChan.

Cheers
Rob
