I d like to highlight an irritating side effect with the side scrolling property of a small window. Can we please disable the mouse scrolling for the small window completely? Its perfectly possible and comfortable to only scroll it using the arrow keys. Otherwise this infinite rotation happens pretty often in the thick of a game just because you accidentally scrolled it and then quickly escaped the small window upwards. As a result you can not really expect the secondary camera to reliably observe a single selected position. Sooner or later it does the rotation thing. Note: i cant use the mouse wheel button to rotate the camera because it is broken so i have to make use of cursor edge of the screen scrolling option.
