Sorry for the late reply, but I skipped over this e-mail. I have
commented your e-mail below.

Please, *do not* reply to digests, _in particular_ do not leave parts
that have nothing to do with the mail you're answering to.
I do not understand, is this a 'digest' (pygtk@daa.com.au)? Who should  
I send the e-mails to otherwise?

If you ask for help, it is your job to put together some code that  
runs,
isn't huge and reproduces the problem. Attaching a single file  
depending
on tons of imports doesn't help.
No problem, I will will provide a self contained example. Attached is  
a simple example executes two methods. The first, effective_dialog(),  
creates a dialog which is the appropriate size. I created the most  
basic dialog for this. The second, deffective_dialog(), creates a  
dialog which is too large. This is how I implement it in my program,  
and it is causing problems.

On the other hand, I recognize if you do the job if isolating the
problem, you'll maybe solve it yourself.
I think it may have to do with the way I create the buttons in the  
create_buttons_with_image() helper function.
