I hadn't noticed yet, but making CVM use the Grid subsystem made me lose scrolling. It's fine because that scrolling was "artificial" in the sense that it was provided by curses, not Collapse OS and I prefer having something that closer emulates a real machine. However, CVM didn't properly clear the new line when entering it. Fixed. Scrolling behavior will come back when it's implemented in the Grid subsystem.
