Question: media buttons
Media buttons (F7, F8, F9) don't work properly with Music app. It's just ignoring my inputs. It works in browsers, but not for Music app. I tried a lot of things that I found in discussions on this theme but it's not working properly. Sometimes it starts functioning from nowhere and stops as it started, from nowhere with no signs. It's a real pain to go to Music app every single time I want to skip or pause a song. First thing that irritates me is that when some media is playing in my browser or in QuickTime player buttons don't control Music app anymore like it used to but it controls that media, media that was played latest. It's really really bad. And now this bug. It's annoying. Really. Too much bugs and bad decisions around media buttons.
