I had a similar problem for a while that might be applicable.

In IE, when clicking on my toolbar link for FlyerTalk, the page is not refreshed, sometimes even if I then hit the refresh button. However, if I use a Flyertalk link to return to the main page of one of the boards (like clicking on the FT XXXX links at the top of the page, the link to the board or specific forum at the upper right, or using the jump to at the bottom.

I didn't do anything special except to kind of adjust myself so that I don't end up with this problem. I naturally started clicking on the provided links or using my back button and tolerating the lack of a refresh.
