I continue to have same problem.

On some occasions (can not figure out why or when) when a thread has new posts I cannot see them - I only see those previously seen. I open the thread with shift key depressed and I see the new posts.

Also, when I open a site from a thread (such as an article or image), the new post marker (yellow folder) disappears as if I just reloaded the page.

I understand that the cache is the problem but can not figure out what is the best setting (using Windows XP and IE 6.0).

Any help please...
