V0.41 is up.
There is a couple of updates.
1) TestController can now remember popup location, it is controlled from the configuration page.
2) The °C issue is hopefully fixed.
3) I have added a lot of # commands, type a # on the command line and see the help window. They are all designed for setting up TestController in various ways from a script.
4) Support for specifying a startup script (There was already a default), see .bat file for more information.
