Here's an log with all 4 switches, starting when I click on the close
button of the preferences panel :

I've added NSLog(@"bug") in an else branch to my previous hack. At this
point the bogus NSEvent should be sent to the panel and its coordinates
saved as the window geometry, I think.

This is not happening only with SimpleAgenda, I reproduced it with FTP
for example. And this is problem isn't really new, I've been seeing for
some time now.
