Using Viewer (7.6.2.0 on Windows 10 22H2), Full control and File transfer work fine for Windows 10 hosts, and Full control works well on a Linux Mint 22.2 machine running Host 1.0.22q Host.
But File transfer to the Linux host reports "Unable to open directory" and gives an empty right hand pane in the File transfer window, Terminal gives a black window which immediately closes and Power control doesn't appear to do anything.
What gives?
