Smooth scrolling and window positions

Hey, so I just installed Windows 7 in VirtualBox, and so far I have two annoyances.

The first one is small, but Windows doesn't seem to remember window sizes and positions. Do I really have to resize my browser to the full height of the screen every time I open it, or am I missing something?

The second, which is amazingly annoying, to the point where it's almost painful, is the complete lack of smooth scrolling. It's ridiculously jumpy and resistant. Somebody please tell me I'm just missing something here?

 

Just reinstalled for unrelated reasons, and I noticed that BEFORE running all of the software updates, smooth scrolling worked fine. Hm.
