I've responded to this thread http://www.vbforums.com/showthread.php?t=651485 and ever since I did I can't access it.

Well, I can, but IE seems to go into some sort of loop consuming 50%, at least, of the CPU and gobbles up memory (over 330 Mb and counting!).
It only happens on that particular thread - I can read and reply to others with no problems.

I assume that it's something 'local' or is there a misbehaving Ad somewhere ?
I've cleared cache etc.

Strange
