Hi Eivind,

I believe this is a known problem. You say that you did not see this 
with 22.0.50.1. I can not explain that, but I know I saw problems very 
similar to those you have seen when I used 22.0.50.1. They occured a bit 
randomly. However I always have the windows taskbar at the bottom of the 
screen.

The reason for the problem is that the Emacs window (frame) is not 
really maximized on MS Windows. And this is because the display engine 
in Emacs currently is not tested for taking care of half lines that 
maybe could result from making the it maximized. (At least this is how I 
have understood Kim's answer earlier on this. And I believe Kim here.)

I have however been testing a very simple patch for this very long now. 
I have seen just one minor problem (I always use maximized windows) and 
no one else using it has reported any problems at all, but this patch 
will surely not make it into Emacs 22 since people really want to make a 
release very soon.
