big blank box. Help? I can't see who is online. Also, when I chat with someone, I can't see what I'm typing. I usually have to use my facebook inbox. Also, when I click to see someone's photo, it loads at the bottom of the screen and is really tiny, so I always have to refresh the page to see it normal. Also, I can't tag myself or anyone else in photos. These problems come up only when I'm using my computer (a Macbook Pro), but when I use someone else's computer (even if theirs is also a Macbook Pro) everything works completely fine. What should I do?
