I have a very stable system and internet explorer 9 (dutch) and all updates installed. Sometimes when I'm on sevenforums and have multiple tabs open I'm going to another website using: addressbar, homepage butten, favorites. None of them work (sometimes) . Only that tab keeps loading and I have to click on X on tab (it says still busy).
It happens about every 2 hours and then all sevenforum tabs are freezing. Click on a link insite sevenforums works however (if it is not already freezing).
Did try to disable add-ons. Even started internet explorer without add-ons. Problem is still there. And only seen that with sevenforums. all other tabs are working fine.
