Myst IV Revelation

Hint: Darn Mouse!
When playing several puzzles you will find it helpful to ESC to Games, Options, Cursor Options, move the Transparency Slider to 0 (Zero), and the Cursor Speed to 100. You will be surprised what you can see and how fast you can move. Try it on the dials in the Monkey puzzles in Haven, the sliders in the Spider Chair Panel in Spire, etc. Cursor settings can be restored, change the sliders or reset Cursor to Defaults.
