on my iMac (intel) Safari always hangs on me. It seems like its always the same periodic 3-4 days it will start to do it. I try to load a page and it just sits there, I might have a bunch of tabs open and I'll hvae to close it and open it back up because nothing will load. Sometimes i have to click on the airport shut that off and open it back up again. can i stop this madness, it's really annyoing. Is there something i can fix?
