[LyX1.6.3/Vista] Setting prefs shrinks LyX window

[Jannick Asmus]

Changing the preferences shrinks the LyX window after hitting the OK 
button in the preference dialogue. I change the settings every now and 
then, but it is kind of annoying to scale the LyX window up every 
time.

Using LyX 1.6.3 on WinVista.
Do you have any suggestions to amend that - or is it a nice to have?

Thanks as always !!!
