[Plugin: WordPress AdBlock Blocker] Breaks WordPress 3.1 Functions

After upgrading to WP 3.1, this plugin started messing up some of the functions. Namely the widgets could no longer be edited, and pictures could not be uploaded. I would get an error on the page in IE which was telling me that some mouse hover function didn’t exist or something. When I disabled this plugin, all was well. It used to work fine, but not any more.
