Query: Note to MacOS Uers: Requires Classic Mode (does not work with Leopard!)

Please note that the Mac OS version requires use of Classic Mode, and it does NOT run under Leopard (10.5 and later). Fortunately I test-installed this before putting it under the Christmas tree and discovered it's now truly non-functioning.I remain unclear as to why manufacturers don't do simple OS updates for popular titles, particularly when attached to such classic figures as Dr. Seuss, but it is caveat emptor for kid software. I think I've had about 50% of the titles we've bought over the years actually work.
