For about a month now I have been noticing a weird quirk in the forum. It seems that, at least with Firefox on Windows 7, when I am reading a post, the post "keeps loading" as if it is never completing the page load, with a spinning icon. And when I hit the back button, the browser will not go back to where I clicked to read the post in the first place. If I look in the history, it appears that the "back" target is actually a forwarding page to the post that I am reading. The only way to go "back" is to click a link to where I was before, in essence, go forward.
If that doesn't make sense to whomever fixes forum issues, please let me know, I can attempt to clarify.
It is very annoying behavior.
