Window sizing on Windowmaker

[Piers Kittel <debian@biased.org>]

Hello all,

Have used windowmaker a lot for quite a while on my work and home 
computers, but one thing really bugs me is that only a few certain 
window, when opened, is sized in crazy sizes.  For example, if I open an 
email in Thunderbird, the window takes up the full width but only 1cm or 
so high, but the other windows (such as writing an new email etc) always 
starts up maximised.  Another ex, on my home computer, when Thunderbird 
starts up, it is about 1cm wide, and a couple inches tall - and no 
matter what I do, I can't get those windows to start up maximised?  I 
know my examples are Thunderbird centric, but it affects other programs.

Any ideas anyone?

Thanks very much for your hellp in advance

Cheers - Piers
