I can't see your response either. I am guessing that it has something to do with your response being the 41st post in the thread and your response should be the top post on the next page.
Not that this is acceptable, but the way that I was able to see your post was to type in the reply box and then preview your post and I can see your comment when I scroll down.
I am going to add a post to that thread and see if it posts mine and your post.
Nope it did not work. I am listed as having made a post in that thread in the new posts listing, but when you click on it, it still stuck on the 40th comment which was posted back in August.
