Hi Steve,

Thanks for the reply!  I've been trying all the suggestions I've been
getting through this mailing list, and still have not been able to get the
background of my test image transparent.  Here's the link again for the
image I'm working on: 


I went through all the Gimp options after right-clicking on the image, and
do not see any "add alpha channel" .. I've been browsing FAQ's on the net
regarding the Gimp, and have seen that images that are not in RGB can be
problematic.   Just for kicks, I went and tried to change mode to "RGB", but
"RGB" is greyed out for this image.

Any thoughts?

 This behaviour is the expected. Color to alpha removes the selected color
from all the colors in the image in such a way that when you put the image
above a background of that color you will get your original image.
 To do what you want, and that is to just erase a specific color, you
 1) add an alpha channel to your layer if it hasn't got any yet (right click
on the layer and "add alpha channel")
 2) Select -> Select by Color
 3) Edit -> Clear
