Help A couple issues

[Lennatron]

I'm having trouble unlocking the tablet after the screen falls asleep. I press the power button to unlock but nothing happens. The only way to get the screen back on is to hold the power button which turns it off and then turn it back on. The button works sometimes to unlock the screen but half the time it doesn't. Am I doing something wrong here?

Also the Market always loads in landscape mode ever the though I have the screen rotation lock off.

Lastly, how do I run a non honeycomb app in zoom mode so it takes up the whole screen?

Thanks,
Lenny
