Hi Rick,

with Windows I use fillcolor 255,204,102 with the ink set to srcAnd 
(which alternates with "noop" to achieve a flashing effect).

You can see the effect in my "Image and Words" stack, which you can get 
from page "Sample Stacks" of <http://www.sanke.org/MetaMedia>    

 From the description:

"Learning words through pictures in five different versions: Wordshow, 
Move and Click, Test and Learn, Test with Loop, Final Test. Basic part 
of the stack is an image with polygon overlays corresponding to the 
outlines of objects. Mode "Test with Loop" is an example for an 
instructional programs that allows the repetition of unsolved problems."
