Actually, i have a weird thing where moving the mousewheel couses my camera to roll around the z axis, so that my map ends up upside down. Rolling it again rights it. Anyone know how to stop that?

Your soul...it tastes like chicken

If you're using the 'set camera view' command to zoom with, then its because you've inverted the direction that the camera is looking upside down.

Otherwise, check that you haven't used the same variable for the mousewheel's movement as the camera's z axis roll.
