The original script with the flicker, that was my preferred one since the flickering caught my attention more.
So I never ran a newer version of the script.
It worked great on my last pc, but for some reason it isn't working quite the same on the new pc. It won't stay on top.
So I updated it and without the flicker seems to stay on top just fine.
I wish I could have that flicker back without it dropping behind other windows, though.
BTW: you have done some fantastic work with this. I love the idea of replacing the volume icon and still being able to access settings. This script is now everything the Windows volume control should have always been.
