Debian GNU/Linux 9.9 (stretch)

I've just recorded a sequence of commands into the Scheme window where
I start with a new empty score and make the staff unmeasured add four
quarter notes then create a new measure and repeat until it starts
scrolling. Attached is a screenshot of the screen after it has scrolled
and of the Scheme window.
The script in the Scheme window is this:
8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><

How many "bars" you will need to make it scroll would depend on the
width of your screen.
You could paste this script into the Scheme window and execute it to
see if it scrolls. I've just tested that too.

I'm afraid I don't know anything about gmane (I just looked at its
wikipedia entry but am not much wiser :( )
