The previous post for this issue has marked it as solved. It isn't. There are times when Spotify launches to a blank, inactive screen. I cannot logout or exit from this screen. My only option is to kill Spotify from Task Manager. If I don't do that within a few minutes, my system will crash. I need to uninstall/reinstall to get Spotify working again. I think I've noticed a pattern. If the app is launched and working but I don't use it before rebooting (as sometimes happens at work, it'll be up, but I won't listen that day), the next time I launch it will be fine. But when I use the app, next time I start it I'll get the blank screen again.
