Thanks for the steps. Unfortunately, I am not able to reproduce.

With BiaB Maximized, I open the Style Picker and then Minimize it. It completely disappears off screen. When I click anywhere on the main BiaB window, it immediately appears in the lower LH corner as a minimized window icon, and I can expand it again (see attachment).

I suspect that this is related to your laptop and use of second monitor. I suspect that the Style Picker minimized state is displayed in the lower LH corner of your laptop screen. Can you try opening the laptop to see if that is where it is located?

My understanding is that the O/S decides on the location where to present minimized screens.

I'm definitely interested to know your findings.
