Two issues I've become aware of.
One is that the cover art image or radio microphone image doesn't always show with the first track in a queue. If I refresh the browser window it will show.
The second is that runeaudio.local doesn't work and I have to use the ip address.
I guess both could be network related. ??
PS: Just discovered that runeaudio.local does work in IE11 but not Firefox, Edge or Chrome. (I do have Bonjour installed)
