Nah, I did a test to sustain my affirmation.
I modified PortLink to show buffer size every time Attach is called.
Then I added a 33K attachment to AS_WINDOW_HIDE (and read that message
in ServerWindow of course). Also I put my window to do some
drawing(window became visible after 2 sec). I forced redraws by moving
another window above it, or move it outside the screen edge and back.
The buffer remains at a value above 33K.
bye,
Adi.
