I have created a small house just like the tutorial says. I click the "build" buttom, and then "run". Everything goes perfect with no errors when building the level.
But when I click run, I can't move the camera to any directions with the mouse pointer or the arrow keys.
I remember being able to move on my old Windows Xp computer, but now I am using Vista. If you know the solution to this problem, or if you think that you do, please answer me.

Thank you.
