We weren't rushed. Actually, we were slow. When you have that blue bubble under your name signifying you're a subscriber, you can bump your post anytime you want. That's what your subscription gets you, and we actually feel we were slow on resolving your problem. That's all I meant when I apologized for making you bump.
Thanks for the answers to the rest of the questions. They'll help us set up a comparable test environment to see if we missed something for including our Javascript when using the login tag on a page, so that way you don't run into this issue when you upgrade, and hopefully no one else will either.
As for 'junk', we understand. It takes a long time to be comfortable removing extensions, and we always recommend having backups or a development site to test on first.
Good luck!
