Are you connected via USB ?
No, over wireless link as usual. Since the upgrade to 1.3.39 it gets the error shown above.
There used to be somewhere for listing bugs, but the link no longer works, so must have been either closed or moved.
Just found where it moved to :)
Ok will do in future. Got a response from Michael on the github issues page and seem to have sorted the issue.
