Few questions/problems

1. How do I get rid of the menu bar after pressing Alt, aside from going into windowed mode and back?
2. The Altitude Hold mode, or more likely the Vertical Speed hold, sometimes seems to not respond after changing the desired altitude. In other words, instead of the default 1800ft/s, it pitches up (or down) maybe one or two degrees with a much smaller vertical speed, and changing the desired vertical speed makes it respond properly.
I'm sure I had some more. I'll post them when I remember them.
