Not yet, but this was next on my list. Thanks. I did download the app and open it, but did not go through the shell extension procedure yet. The reason is the right click hang problem has stopped for now and I don't know why. I only did a couple of reboots and disk cleanup and defrag, both did not fix the problem. If the problem reoccurs I will try the procedure and post back.
What would be considered an unusual shell extension that I should look for?
