Ok. I have debugged and run it on Windows (old XP box admittedly), Ubuntu, and Mac.
Latest version is on the download site. I've removed the others as they didn't work on Windows.
Only issue I've spotted is that the transfer buttons (to device, from device, delete) are showing "..." on Windows and Linux instead of "<<" ">>" etc. Not a biggy - the tooltips are still there and the buttons work as expected. Other than that seems to work now.
