Thanks for responding!
Regrettably, the problem is present in all sims.
I'm curious about what your theory is, though? (I'm guessing you figured it could be related to the initial camera velocity when loading a sim? Or whether the camera starts out attached to a moving object?)
That said, I did notice something new:
The *first* time i flip the switch after starting the game, nothing happens - the camera stays put as it should. This happens whether I stay in the default solar system sim or load a different one.
As soon as i touch *any* button on the controller, however briefly, the camera starts accelerating forward. From that point on, it will keep moving forward whenever the enable-switch is toggled on, regardless if I load different sims, until I quit and restart the program.
Any theories or wild ideas are welcome
