You didn't mention whether they expand vertically or horizontally.  If  
they're expanding vertically, it's not a problem with your hbox  
packing, but with how you pack the hbox into the window -- if you let  
the hbox expand inside a vbox, you'll get what i think you're talking  
about.

If they're still expanding horizontally, please post a bit more code  
-- just enough that we can run it and play with it.


Screenshots would help.  ;-)

Do you have newlines in your strings?  Perhaps it's a theme issue?

This one sounds like you need to attach() instead of attach_defaults 
(), and choose the "please don't expand in any direction" options.
