The sound makes the music. Feel free to ask Marcel or Chris personally about the problems and why they are not fixed. Iam sure you will get a friendly and helpful answer.
It is for me like that since months. In 1 of 1000 cases SteamVR closes after closing rf2. But usually i have to close it manually through Task Manager.
I forwarded this to Marcel some time ago. He said it is on the bottom of the "to do" cause i was the only one suggesting this. You would be the third. I dont want to destroy your hopes but i dont think S397 will include it.
