Does Mountain Lion fix the bug that keeps Safari 5 from loading every once in a while? Sometimes I'll be on a page, then go to another page, it doesn't load, and then when I click on the address bar to see if it'll load quicker, a message pops up saying that the pages aren't loading and asks me to load the pages again (I forgot the exact wording of the message). I hit the load pages button that shows up on the message, then all of a sudden the pages load again. It's really annoying when it has to refresh pages like that, especially if I'm watching youtube/netflix, or downloading something. Does Mountain Lion fix this?
