Noticed a little issue lately. Whenever I open the creation kit, load skyrim, and go to a cell, the camera controls get screwed up. For some reason, the spacebar pan function doesn't work and moving the mouse in the window zooms the camera in and out, just like using the scroll wheel. I can't look in a cell without finding an item nearby, double clicking, and rotating the camera to look around. I can't pan at all.

Any ideas?
