Can't Turn

[Thief977]

'Kay, I just downloaded and played with the Dev tools for the past 8 hours, and am now at an impasse. I've created a tiny little, 3 room level I am confident with, but can't test it:
I load up the game, load the level, and try to view my level. But, to my dismay, it appears that I can't turn. I use a XPS M1530 laptop, so I have a built-in touchpad AND a usb mouse hooked up, so it's not their fault.
If anyone can give any advice, it would be much appreciated! I kinda want to test my level, but it is difficult when I can't see half of it!
