Bob, sorry for the delayed reply, I was out of town. I initially disabled both features so I can't tell which made the difference. When I got back home tonight I turned on the spectrum analyzer and checked the Enable OSD box, and the song changing occurred quickly on JRemote with no delays. Curiously, though, when I went into the Id via Windows Remote Desktop Connection, the screen update was very slow. Without any real data, it seems like screen updates on remote desktop are slowest when both OSD and spectrum analyzer are enabled, a little faster with OSD disabled and spectrum analyzer enabled. My remote desktop is connected from Windows 10 Surface Pro 3 via the wifi with the router, Id, and Surface in the same room with loads of signal. It has been difficult for me to remote desktop connect to the Id on wired ethernet. Connecting Windows Explorer to \\Id\InternalStorage using Windows' Map Network Drive has been very hit or miss on one of my 2 Id's and pretty consistent on the other one.
