Sudden Motion Sensor reversed?

Question

Hey there.
I just received my new MacBook Pro and have been toying around with various aspects of it. Everything seems to be in working order save for 2 issues which I hope are easily resolved (despite my being unable to locate an answer myself).
The motion sensor is detecting things just fine - which is all that really matters I suppose - spinning down the hard drive and such. However, I installed MacSaber for fun, which didn't seem to have any issues. However, then I installed a LiquidMac (a fluid simulation program) and NetPong (which uses the motion sensor to control a pong paddle).
If I tip the MacBook to the right, the paddle goes left. If tipped to the left, the paddle goes right. Exact same issue with the fluid simulation program.
So is this a non-issue and the Sensor is just counter-intuitive? Or do I have a problem here?
I can't seem to find anyone with a similar issue here on the forums, so I haven't tried anything besides restarting the Mac.
The other (more minor I assume) issue I'm having is with the Expose system. I found the shortcut controls and they're properly set, however, if either F9 or F10 are pressed (all windows and all application windows, respectively) it places an icon on my screen briefly and does nothing (notably the icon has a "no access" circle with a slash through it, directly below the icon. Interestingly, if I set an "Active Screen Corner" to active "All Windows" Expose - it works just fine - so I suspect this is something I'm doing wrong with the normal hotkeys.

Hello,
I'm new to the MBP myself and am having the same problem with the Motion Sensor, but I can help you with the F* buttons.
In the MBP, there is obviously a lack of space for putting extra buttons to control screen brightness, volume, key brightness, num lock, etc. So, they use the f1-f10 keys. As you can se (if you look down), there are littloe icons next to F1, F2, F3, etc. These represent what the keys do. If you want to use the normal function of the keys, just hold down the "fn" key at the bottom left of your keyboard while you hit the F10, F9, whatever.
Similiarly, if you want to use hte numpad (which normally appears on the right of the keys that are on the MBP, you hold "fn" and use the 6-9 keys, U-P, J-;, and M-/ (can you see those tiny numbers in the bottom right of the keys?)
The reason you were getting the thing popping up on the screen when you hit F9 nd F10 was because those keys are set to control keyboard brightness, and you were in a bright room. If the room is bright, you can't turn on the lighted keyboard. If you go in a darker room, you'll notice that those keys let you turn up and down the brightness of your keyboard!
If you can't understand what any of the other F keys do, just mess around with them, check your manual, or ask here.
