Thanks, I've got it now -- just in time for me to eagerly anticipate 1.03, I see. (:
Speaking of which, are you aware of a bug with Turkish delight and undo/redo? When I replay my own solution for 33 Hard, for example, an unrelated block disappears in the first explosion. I've noticed this on several puzzles, and now I can see that it's also present in 1.02.
