Search for the following sentence in the file "ATLANTIS2.LOG"
on your hard disc drive: "mandalas".

You'll find a section such as this: 

Solution Mandalas 
-----------------
Mandala 1 : numero 4
Mandala 2 : numero 6
Mandala 3 : numero 5
Mandala 4 : numero 1
Mandala 5 : numero 3
Mandala 6 : numero 2 

This is the solution for one of the final puzzles, in which 
you're supposed to click the curtains in the order in which 
you placed the mandalas on the disc during the game. If you don't
remember this order, you'll try forever figuring it out.
