My ActiveX Filtering is disabled and it still does the same thing.
Facebook has been causing problems for EVERYONE who was "suckered into" installing 8.1. I've heard rumors (I can't say for sure because I don't use Facebook) that they're working to update their code.
In addition, IE is the "problem child" of browsers, and you'll have much better results with almost EVERYTHING using Firefox. It doesn't use ActiveX controls, which cause more problems than they will ever prevent.
