Greetings,

even though I'm using Xubuntu 16.04  I nevertheless use Gnome's "gthumb"
as image viewer.  However, I cannot find a way to keep "gthumb" from op-
ening a fullscreen window when fired up.

So I ran "man fvwm"  and checked the stlye options,  but "MaxWindowSize"
isn't really what I want, because it prevents me from later manually in-
creasing the window.  Is there some way to just specify an INITIAL wind-
ow size or even window geometry?

Sincerely,
  Rainer
