Charles,
Sorry we are just now responding back on this thread.

Before we read your response back on the 5th, we took action and shut the problem forum down and moved all the topics & posts over to an archive forum.

We then created a brand new forum and moved the topics back into this new one from the archive. All works fine with this new forum and its content now. Response for new posts and replys is great.

We have the old "broken" forum turned off. It indeed has some broken pointers or indexes or maybe a structrual problem somewhere. It still has the extreme response problems even today and it has only a couple of topics. So the problem was not related to the number of topics/posts that it contained.

Let me know if you would like access to the broken forum for testing and we'll set you up.

Thanks!
