Bill,

I tried Chipp Walter's solution and I get a "Rev has unexpectedly 
quit" message at the line:

        import snapshot from rectangle tRect of window tWinID

Don't know why. According to the docs it should work. Could this be 
an OS X problem? (Rev 2.2.1, Mac OS X 2.3)

Could you just use a single circle graphic (with a text field below) 
and then just set the background color of the circle graphic as 
needed?
