A couple quick 8.1 questions.

I just recently moved from windows 7 to windows 8.1 and I have a few questions.

1) when I try to access the app switcher, the app rectangle previews are cut off. I put my mouse cursor in the top left hand corner and drag down but I don't get a full bar like the charm bar on the right side. I get about a quarter of the rectangle that I can click on and can't even see which apps are there. Anyone else see this problem?

2) need a way for windows 8.1 to remember all my window sizes and positions.
