Just joined-First post! Converted over to MacBook Pro 13" in 2012 and so far love it...including the built in trackpad, BUT...On some websites during sessions in Safari, I find that when I use the two finger swipe to go back to the previous page, it goes to a white screen and after that even the back arrow button won't return to the previous page. I have to highlight the website and hit the enter key again and start over. What the heck? If you know the fix for this weirdness, please give it to me step by step, as I am new to MacBook Pro. Thanks!
