When I finally got an Adobe tech support person to talk to me, he said it'd cost $39 for on phone advice and I should go tohttp://forums.adobe.com/thread/886700, which I did and it says this is a common problem and offers some user ideas on fixes, chief among them disabling "protected mode" in general preferences. Some forum participants said this worked; it hasn't yet for me, but I'm trying reboots, etc. It so far has resulted in reducing the freeze slightly so that I can turn off the program from the screen's X box. Still working on it. See what you can do.
Thank you for the information I have tried this and it appears to be working fine now.
