Program window height changes according to components displayed: can cause mixer, piano to disappear off screen
Win 7 / Win 10. MS 3.2.3 (official)
Under certain circumstances the program window increases in height to accomodate the components rather than maintaining a fixed height. This can result in the lower part of the window disappearing off the edge of the screen.
The best way to see this is with a smaller screen laptop (15 in. say), or by reducing the size of the program window. Select some text in the score to get an Inspector display, then dock the mixer by dragging it to the bottom half of the Inspector so that they are stacked (not one behind the other). Now display the Piano keyboard.
Expected result: Program window height stays the same.
Actual result: Window height increases to accomodate the Piano.
