Every once in a while Safari freezes on me. I can click things, but nothing happens. Actually, to try and be as clear as possible, like if I press the back button, what's shown doesn't change, but if I hover my mouse over things and I'm familiar with the page I was trying to go to, I can tell that it actually did go back because it changes to the hand over where I know links should be. But it still looks like the first page. I can't get out of that no matter what I do, and I end up having to quit Safari to fix it. It's just annoying to have to do that. Anyone else have a problem like this and know what the cause and solution might be?
