Try this: Make a S_R window. Drag another window on
over the top portion of the S_R window.
Now ScrollRaster the S_R window towards the bottom of the
screen and try to handle refresh intelligently.
The only reasonable solution is to repaint the whole
window in JAM2, or clear then fill with JAM1. Both yeild
excessive amounts of flickering.

It does not update the damage lists to account for the
obscured (sp?) portion of the S_R.


Thanks for the monitor-damage details.
