1920x1200??!
WHOA!
You surely have a powerful machine! I run at 1680x1050 on a 20" widescreen...not great performances, but looks very good. I think the menu.cfg file contains some settings related dimensions ad position of various tools and dials. (at least that's the file almost every mod which changes those things replaces).
But I'm not aware of anything for your porblem, sorry..
