I played around with it a bit more. It seems like a combination of actions. Here’s my current observation.
Suppose I am scrolling down a styles list of a few hundred. More than one screen so that I need the ability to scroll. All works fine. Then I double click on a style to hear it. Give biab time to build the parts. I can double click any other style on the ones on the visible “page” but cannot scroll at all. Maybe that’s the desired behavior?

If I hit the ok button after a delay I can set focus on another style and can again scroll.

When “frozen” I can also try to drag the up down scroll bar in the list box (or whatever it’s called) of styles. That shifts the entire list horizontal position a bit but frees up the scrolling

As i mentioned, the hardware (mouse keyboard) are fine everywhere else.

It’s not the end of the world, it’s just not the behaviour I’m expecting. It seems a non-desired thing.
