Yeah.  That's why 0 is bad--0 is black, which is used in /many/ 
applications.  1 is "almost" black and is used in a far smaller number 
of apps (mainly in gradients, so it's a much smaller portion of the app).

Set the color key to 0 and run:

xterm -bg black -fg purple

and do the alt-tab'ing thing you described for a very low-resource 
transparent xterm.   Allows you to write Myth patches while watching TV.  :)
