404 Error/Invalid Thread

John, there have been several threads that I've tried to reply to, I can't remember which ones, but I remember the one I tried to reply to yesterday, it was called WebBrowser Questions.

I posted the answer to that thread, pressed the submit button, and it took forever to load. Than finally, it would take me to the 404 Error page. I'd click Refresh and it would say Invalid thread, although the thread was still there. I tried repeating this several times as well, same thing happened. So I had to create a new thread to answer the WebBrowser Questions thread :rolleyes:.

Do you know what could be wrong?
