I have noticed that the buttons on the remote stop working if the screen loses focus. Clicking on the window cures it but is not ideal. I found that I had a notification window that would pop up from time to time and steal focus.

I'm using the official JRiver Remote and it's strange. About half the buttons stop working for me when the screen loses focus, but often not immediately, which is very strange.
I have to use the loopback feature a lot (partly because Netflix is anti-social with it's API), so I often turn on JRiver, set the loopback, and then go into another application (a game or web browser). I've noticed that the stop button always, always works no matter what I'm doing, but the pause button (for example) stops working when JRiver loses focus.
Where this gets dicey is the volume control. It stops working for me when JRiver loses focus, but not everytime, and not always immediately. It seems almost random. Sometimes I'll start a game or netflix movie (in a browser outside of JR), and I'll be able to adjust the volume just fine for a while, but after a few (or 10 or 20) minutes I can't adjust the volume anymore. Sometimes, though, as soon as I start the game/movie I can't adjust the volume, which is a pain (it's hard to know how loud the game is going to be until you get into it).
If anyone on the JRiver side wants to try and reproduce it, start loopback from standard view and launch a video game (I've been playing a lot of Skyrim lately, but the problem occurs with every game). I've never played anything where the volume control wasn't non-functional by the end.
I've never experienced the situation where JRiver loses focus during movie playback (i.e. the remote always works when I'm playing something inside of JRiver), but it definitely starts behaving erratically during loopback applications. I know it's a slightly different problem, but the root causes are likely related (i.e. related to a loss of focus).
EDIT: Sorry Jim, didn't see your reply. Glad to hear you're "on the case"
