Safari slow and freezes when loading pages
Hi I've been having a problem with Safari for the past few months it frequently freezes when loading web pages, sometimes it will eventually load, other times it wont. the blue progress bar in the address bar stops on about 10% with a plain white page it doesn't happen all the time but disturbingly it happens on pages as simple as Google search, not just data heavy sites. other symptoms include having to click links several times to get them to respond and I get the you are not connected to the Internet page when I go to some sites only to try another page from my bookmarks and it will load perfectly.
Any help greatly appreciated its driving me nuts.
