I have XP and recently downloaded SP2. Now on certain websites when I search and click on a thread it works like normal, but when I click the back button to go to the other search results I get a "page cannot be displayed". Refreshing does not help either. I am not having problems with this site, but on the www.bobistheoilguy.com forum for example it does this. It only started doing this since I installed SP2. What do you think could be the problem?

 

Still having this page displaying problem, which happens randomly. Anyone else experiencing this?
