This message is pertinent only to those of you using edd/dm 2.0 or later.

Yes, it should work.  Unfortunately, as David reported, it doesn't! 
To fix it, look in rti/dynamic_graphics.c and apply the following change:


int evalColoRule( valStr, pComel, comparator)
	.
	.
	.
        if(isdigit(*valStr)){

********
change the last line to be 
        if(isdigit(*valStr) || *valStr == '-'){
********

This is a quick fix, but I've tested it and it works.  I'll try to rework
the color rule comparisons soon and will come up with something better.
Thanks, David.  I'm not surprised there was a bug, but I'm surprised it
took so long for someone to notice :) !
