Bernd’s description largely mirrors my experience, with the exception that I cannot drag the window at all as I have to run Roon in full screen mode.
I also see the scroll bar slider briefly disappear when I go back to the album view after clicking on a particular album. It then reappears, but doesn’t work. It doesn’t matter whether I select the album to play or not. I also lose scrolling of I do a search, or follow a link to a performer or whatever, then use F1 to go back to the album view.
It is W10 with all updates installed when proposed by Microsoft. The PC does little else except act as a big screen remote control for Roon and as a web browser. It has VLC and JRiver on it, but they are normally closed, and are there solely for video playback.
I hope this helps.
