Actually, it looks like we've tracked the problem back to internet accelleration utilities that run your requests through a proxy server. As I mentioned in the other thread, you need to turn off these third-party programs and add-ons, because they can cause problems like this. Any time you're visiting sites that are dynamic in nature, you're going to run the risk of this happening.
So why does it only happen here? Probably because we have a great deal more traffic than some of the other forums you might frequent, which will exacerbate the problem. Anyway, both you and Troy seemed to be using IP addresses that are traced back to "MarketScore.com", which is a division of Symantec. It sounds like their internet accellerator is what's causing the problem. If you're using that, you should probably shut it off.
