It is, but only when the camera is already active, ie MMB has been clicked. However, holding down the MMB and dragging while the camera is not active, is still available. The programming would be like:
- If MMB pressed and MouseMotion is greater than 5 pixels -> Start Scroll.
- If the MMB is release before the mouse has moved 5 pixels, then enter camera mode as usual.
- If MMB pressed and MouseMotion is greater than 5 pixels -> Start Scroll.
- If the MMB is release before the mouse has moved 5 pixels, then enter camera mode as usual.
