Hi David

Well, I'm happy with a refresh rate around 30Hz even with 20hz I'm okay, 
even when it differ between those rates. But with jalv I get 2hz, and 
that is a way to low for my needs. That fact leads me to the questions I 
come up here with.

That will be very welcome. :-)

As well I would love if you accept Robins patch to set the signaling 
rate for engine /UI communication.
