Hi all,I am currently having the same problem.  Can't wait to test this script to see if it works!! I wasn't able to find the script at all in the URL posted earlier in this thread but I was able to find it here (hope it's the same one):https://systems.cs.uoregon.edu/wiki/index.php?n=Help.MacAppsAdo...

Editing the XML worked great for me too.  It was the only way I was able to change the colour of the actual 'filled in button' part of the radio button.  Thanks so much for this!
