internet explorer back button on new forum results in "expired page" warning

anyone else running into this?

I started to see it about 5 months ago with the latest internet explorer so I switched to chrome

I figured i'd check with the new forum now the back button is completely unusable

If I want to troll a particular forum discussion area, I have to open the posts in new tabs otherwise i'm clicking to expand the discussions after hitting back button twice
