Thank you! That did the trick.
I have the Nik plugins as well as On1 and Topaz. Every time there is an upgrade to one of those products I end up with duplicates like slaflamme shows in the screenshot at the front of this thread. I know how to get rid of them, but why do they occur? This has been driving my nuts for a long time - on both my Macs - but I have never been able to figure out why an upgrade, or reinstall, doesn't replace what's there rather than create an additional copy?
