Post History Bug?Follow

I just noticed that when clicking links in my post history page, if the link is to a thread I created, then it only takes me to the thread index page, and not to within my thread. However, if I click on a link for a post I made within a thread, it works fine by taking me directly to my post within the thread. I'm not a premium member, so this may be an intentional function, but perhaps an admin and/or someone who is premium can check it out.
