I agree that Myst IV drove me kindof crazy...the Mangaree puzzle where you had to get each one into the right nest was the one I had sooo much trouble with I finally gave up and got a saved game. Also Schizm, Mysterious Journey...the puzzle in the fog... I knew what to do but kept falling and falling...after days of trying, I finally got through that puzzle. I didn't have near the trouble with Rehm 1 & 2. As to Lighthouse just installing it for XP today is a puzzle in itself and I haven't gained the courage for that yet, lol.
Life is like a hot bath. It feels good while you’re in it, but the longer you stay in, the more wrinkled you get.
