One thought: I've de-saturated some images with CA and sometimes found that 
by selecting the "fringe" I could selectively desaturate to a neutral gray. 
I agree that the sliders don't seem to easily just "erase" the issue.

Yes, I'm trying to use LR and several other programs that claim to 
remove CA.  I have never been able to use any of the Adobe products 
to remove CA.  The sliders go from Red to Green without ever being 
neutral!!  So far, all I can do is use Gaussian Blur at a very high 
rate, Edit, Fade Gaussian Blur (Color) and then use the History Brush 
to brush out the red, green, purple and yellow edges.  :-(   It takes 
far too much time and I have far too many photos to correct them all.

I agree, I need to go back with my M8s ;-)  I loved China, anyway.
