Date: Tue, 09 Sep 2008 12:51:22 -0400

CVS Emacs on Windows XP sometimes fails to draw the contents of a new
frame.  To reproduce, run "emacs -q", and evaluate this form:

    (let ((frame (make-frame)))
      (make-frame-invisible frame)
      (make-frame-visible frame))

The new frame's contents will not be drawn.  Typing "C-l" in the new
frame does not cause its contents to be drawn.  You have to switch focus
to another window and back again before the frame's contents are drawn.

This bug (also reported as bug#1748 and bug#2524) should be fixed now. 
It was due to a poorly implemented redraw optimization within Windows, 
which I have worked around by using a non-standard paint message 
internally in Emacs.
