window sizing?

[Jeffrey Ross <jeff@xxxxxxxxxx>]

I've recently noticed that when programs open they are opening to a size 
larger than the screen resolution.  I've noticed this primarily with 
Firefox and with Evince (PDF reader).   Basically the bottom and the 
right edge of the window is off the screen.  I can manually resize it, 
but how do I adjust it so it doesn't extend off the screen?  My 
resolution is 1280x1024.

TIA
Jeff
