I have the macbook and for the life of me cannot figure out how to open another web browser. Sometimes I need to web browse multiple times at the same time. Another problem is – I cannot get my screen to expand in full screen mode. I used the bottom right-hand side corner to expand the window, but it’s still not in full screen, so the bottom is cut off. Help! Thanks.

Everytime I try to watch a streamed video, like a youtube clip or facebook clip the window freezes and it says it is "Not Responding." I think this has something to do with the fact that Windows 7 runs as a 64-bit and the videos run through a 32-bit system or something to that effect. I have tried downloading Adobe Flash Player 10 multiple times and it says I have downloaded it correctly but the problem persists.

I’m trying to install Windows 7 and it says it will restart multiple times doing so. Well, when it restarts, my computer asks me to press any key to load from CD/DVD, and Windows 7 starts over.

Why?
