windows10: musescore blocked by hidden window for preferences
in Windows 10 start musescore 3.5.0 (just downloaded, reset to factory settings). Bring up the dialogue for preferences and make some changes. The Window is too big to show the apply button. Grab the window top border with the mouse and drag it downwards. This makes the window disappear and musescore is blocked. It can only be killed by the task manager.
