Bug in 1.6.3svn: The main window moves when I apply preferences

[Helge Hafting]

I noticed a little oddity today. When I apply preferences, the main 
window jumps a little up and to the left.

This doesn't always happen, so may be hard to reproduce.
Clearly, the window must not be maximized, and it seems like LyX should 
be started with "restore window layout and geometries" set.

A small problem, but it looks like LyX is doing some unnecessary work here.
