Download the demo from this URI: 
http://wood.sandbox.cz/zork-grand-inquisitor/
and install it using the instructions provided on that page (for ZGI Demo).

Notice that when you move the mouse in in-game menu, the screen blacks out. You
may however find the correct button (New Game) by hovering the mouse over it -
cursor will light up.

When you hear music, you can pan the view by moving the mouse to left or right
side of image. Screen draws during the panning, but then blacks out.

Using Fluxbox window manager and switching to some other desktop and back the
screen remains drawn correctly until user releases the switching key.
