It's time we I said something nice about 4.0. I'm really enjoying the stereoscopic pictures (see note below) and the maps are light years beyond the old Logos maps. The illustrations are sometimes good too (can't bat 1000). Thanks for the visuals (and I'm not particularly a visual person -- as Liza Doolittle says in "My Fair Lady", "Words, words, words" (though as I recall she was tired of words and wanted action).
NOTE ON STEREOSCOPIC PICS: I'm wondering why the stereoscopic format is retained. I don't know of any way to view these as stereoscopic on a computer screen. One of the pics should be sufficient. I remember these old pics. My paternal grandmother had one of those old viewers. To a kid they were amazing. They later came out with a plastic version which used disks -- perhaps they can still be found if one looks diligently.
