First few characters of top line sometimes does not refresh correctly.

Just happened upon this. Pretty sure it's just a typo, and no idea how significant it is, but I thought you might want to know about it. Durdraw crashed (I think while I was changing colors. Not 100%; it was abrupt.) and printed an error message to the console notifying me that 'selt' is not defined in durdraw_ui_curses.py. :
