Audirvana shutdown problem

I have experienced a persistent problem when I close Audirvana in Windows 10. More than half the time, Audirvana remains resident in memory, preventing me from re-opening Audirvana until I close the background Audirvana using Windows Task Manager. I was hoping this would be resolved when Audirvana 3.5.0 made its appearance. Unfortunately, the problem persists. I know how to work around it but it is somewhat annoying to have to go to Task Manager to complete closing Audirvana. Are others experiencing this problem or can I assume that it is confined to my specific computer?
