No, the app itself is still running in the tray. I have a set of Corsair wireless headphones as well. iCues is running, and I can navigate everything. IE - I can pull up the graphing and see the Fan speeds. If I go to the settings, and then click restart... I can go back to graphing and after a few seconds for the restart, I can see it "restart" and everything starts to work normally again - until it doesn't. Last night I started up Battlefield V and I immediately knew it was "hung up" because I didn't hear the fans start up. So I minimized BF, brought up the iCue app, restarted the process, and after a few seconds the fans spun up and stayed pretty much at the max 98% my entire session according to the graphing. However, after I shut BF V, etc... it stayed at the 98%, it didn't throttle down. So I restarted the service again and it immediately slowed everything down to where it should be.
The only other app I'm running is Afterburner for my video card as I prefer it over Precision. I do have CPU-Z, etc... but none of them are running at the time of the issues.
