frames resizing themselves, emacs 21.1

[Hein Zelle]

Hello,

I've recently started using emacs 21.1 and encountered few problems,
except for one I can't really solve:

when I start emacs, the first window(frame) initially gets a larger
size than that specified in my .Xdefaults file: 80x45. The initial
size seems to be something like 82x47. Before it is done initializing
though (I'm not sure if this is before or after reading my .emacs
file) the frame is resized to 82x45, automagically.

If I then open a new frame with find-file-other-frame, the new frame
is opened with 82x47, and does not get resized.

I've read documentation on variables default-frame-alist,
initial-frame-alist and minibuffer-frame-alist, but can't figure out
what to do. I don't specify any of them in my .emacs file.

If I don't change anything, these variables have the following value
after starting up:

default-frame-alist's value is 
((vertical-scroll-bars)
 (tool-bar-lines . 0)
 (menu-bar-lines . 1)
 (width . 80)
 (height . 45))

initial-frame-alist's value is nil

minibuffer-frame-alist's value is 
((width . 80)
 (height . 2))

Can anyone explain to me what's going on here, and how I can obtain a
consistent window sizing with .Xdefaults and emacs configuration, for
both initial and later frames? The only thing I can think of is that
it has something to do with the recently added 'side borders', that
would explain why my frames are 2 wider than requested. I don't
understand the difference in vertical size though, especially not as
it is different for the initial frame and later frames.

Please send reply's to hein@icce.rug.nl, as I am not subscribed to
