I was already using only a normal mouse yesterday because the 3D mouse was my first suspect. Now I got the problem resolved by also shutting down the 3D mouse software that was still running in the background.

I think you should look into this and figure out if the game takes any commands from the possible game controller in addition to the arrow keys and middle mouse button as the problem appeared with a steering wheel too.

When opening a level, the camera scrolls to the top left corner like there were left and up arrow keys pressed except they are not. I tried rebooting the computer, disconnecting the keyboard, also disconnected the 3D mouse I usually have connected to my computer. It still does the thing same every time.
