Object error on Vbulletin sites

[60wag]

One of my computers has developed an odd problem - any Vbulletin based site that I go to gives me an Object Error message that returns whenever I try to close it. Non Vbulletin sites work fine. I've tried flushing caches, cookies, temp files and still have the problem. The error message does not give any specific number code to localize the problem. Any ideas?

solved

I finally figured it out - it was some lame IE add on causing the problem. I disabled a thing called "privacy safeguard BHO" in the manage add ons men and the problem is gone.
