Here is one thread I am experiencing the problem I have described earlier in another thread when I use Display Mode set to "Threaded Mode":
Birds by DA55-300mm
Now, here is what is happening: under the post by 'cupic' (subject "There fabulous.Looking back..."), there is a link "More replies below current depth...".
When I click on the "More replies below current depth..." link the message view simply resets to the original post and the tree does NOT expand. The same happens if I hit "Next" to see the next message from cupic's message. The behavior is identical with all skins.
In Linear Mode I can see all posts no problem.
The same behavior is with both Mozilla Firefox and Internet Explorer.
However, if I log out and then navigate to the same thread it DOES work just fine!
Can anyone else reproduce this?
