Hello:
Is there a single instance option? If I have JRiver open on the desktop, and initiate playback by clicking on a music file from a hard drive, another instance of JRiver is launched. It can get messy.
Incidentally, I am experiencing the white "flash" when going to Theater Mode. I'm running Nvidia 367.57 drivers on a GT730. I get the same thing using the default Nouveau X-Server drivers. Anything else to try? Thanks in advance.
