Putting a period adjacent to the link leads to the period being included in

Hi Ric,
The simplification is something I will run at in the next couple of days, but
as far as the 'chatting' between the windows with different views for different

I did exit'' in the jijx page. That seems to work and there is no
lingering task out there when I can successfully launch jhs801.
But, what I most recently reported was an alternative to rebooting if I try
to launch directly by double clicking on the jhs801 icon. I mentioned it

Sounds like there might be a problem with the 801 Mac OSX app launcher
for JHS. I won't be able to verify this until the weekend. Perhaps
other Mac users can dig into this.
Meanwhile, probably better to use the JHS8 with the method that works
and wait for the dust to settle.

By default JHS701 and JHS801 both use port 65001 so you can only run
one of them at a time. If one is running, starting the other will fail
because the port is already in use.
It only makes sense to run that ps command if starting a JHS server

Since J is single thread, those globals will not cause any
