Yes, even if each time not always the same size: sometimes more, 
sometimes less. I have quantified this in about one line (or, if you 
prefer, about the height of the minibuffer). I would say 10-20 pixel.

I am afraid, I wasn't able to use that function.. How to evaluate it? I 
tried a few command but they didn't work.

I have attached a tar-ball with a few examples of desktop file. They 
have been obtained in this way.

First I removed the current desktop and history files. So I started 
Emacs and moved it so that it was centered in the Windows desktop (I 
tried this with the Cygwin build..). Then I closed Emacs and it asked to 
save the desktop. Yes - and this generated the "desktop-00" file. Then I 
restarted Emacs and closed it obtaining the "desktop-01" file. I 
repeated this 2 times obtaining "desktop-03". After repeating this a few 
times I obtained the "desktop" file: now Emacs frame is conspicuously short.


Ciao,
 Angelo.
