[openbox] resoultion versus size

[Bora Dal]

Hi!

I have LXDE desktop environment with Openbox window manager on a Ulite
distro. I am changing the resolution through

 /etc/xdg/lxsession/LXDE/default
configuration file

I am trying to fit as much as possible to a high res screen

Strange thing is no matter how high I set the res., the sizes of
windows, text on windows, icons also get larger as well. For example
on 1024X768 7 size fonts become much much larger(like size 11) if I
set the res to 1680x1050. Is there a way to keep them small(size 7)
even if I increase the resolution?

Please let me know if I wasnt clear...

Thanks!

Bora
