Well, i opened up my browser object and it showed some of them as 'broken', so I deleted them and the site seems to be working fine now.
On Internet Explorere click the "tools" tab, then chose "internet options".
From there chose the browser history "settings" and chose "view objects" to see if anything is broken.
You might not wish to delete them at first, should any be broken.
As it is wise to find out what exactly is going on.
Mabey google the broken objects?
