     All of the windows in a screen share the same bitmap (at least for their
visible portions, which is what you're interested in).  So, if you want to
double buffer one window, you've got to double buffer all of them.  The entire
screen gets flipped all at once.  So, unless you first copy the contents of the
entire screen to the hidden buffer, the other windows are going to flashing on
and off as you flip bitmaps.
