* Don't invalidate anything in offscreen windows. NetPositive is doing

Browse Source 
slightly strange redrawing, including scrolling the offscreen view
  that it uses in "flicker free" mode (which is the default). Invalidation
  does not work in offscreen windows, since the client thread is not running
  and certainly won't redraw anything. But that will leave a non-drawable
  region on the app_server side of things. Simply don't invalidate in
  this case. From what I have seen, redrawing in NetPositive seems to
  work fine now.
