I have been having this problem. That big, square, right side pop-up above recent discussions had started dominating to the point of great irritation. Has been freezing every forum page/post/thread until its pop up finishes loading. Yesterday it briefly went ballistic; the pop up now remained in foreground, blocking the page images and text
I wanted to see. Then it kept running its audio over and over. Incredible.
I'm running IE in Win7. Could find no evidence in my browser or Win7 programs of a Java to turn off. A search for a download of AdBlock that worked proved futile, mainly a bunch of reviews, -- nothing for IE.
Finally found a solution. In IE I clicked on IE "Tools" - Popup Blocker -settings - "change blocking level to high." That seems to be working.
Now, the contents of the square opens but remains frozen--no audio no video.
What a relief it is.
