I really loved "easy rotator" but I realized it was responsible for the screen options freezing in all of my edit posts and edit pages views.
After its installation, screen options stopped working (expanding-minimizing menus and check more screen choices)particularly in the edit post and edit page view. Anywhere else was working properly. So I was forced to uninstall it although it was exactly the plugin I was looking for.
I would be really happy to now you resolved this problem.
P.S. I'm working with 3.4.1. WP version
