--- Comment #15 from Jonas winehq@jonass.user.lysator.liu.se --- Seem like something changed with Wine 10.17. Now the Pegasus window can be minimized. However, it seems like the next mouseclick is "stolen" and Pegasus is restored. I say "stolen" as I would expect a mouseclick in another windows should set focus to that window, now it only restores Pegasus.
