Universe canvas is partly hidden by Windows task bar, can't move or resize it

[Adrien79]

The very first examples (rocket animation) from How To Design Programs, 2nd ed., do not fully work on Windows 10:

• the window created with animate is partly covered by Windows task bar on the left side of the screen
• even if I can move the task bar away and see the window in full, there is no way I can drag or resize it

I tested the same example on a Linux station and everything works fine: the window is displayed at the top left corner, then I can drag and resize the window as usual.
