Thanks for replying, AlexsMom--I'm glad to know I'm not missing something, but that is a bummer. We've found a couple of bugs from time to time but they did warn us and it hasn't been too bad. Given the cost and because it seems like there are quite a few people using it I'm surprised there still are bugs; I would think they would have worked them all out, given that the material probably doesn't change much over time. But overall I'm happy with it and glad for the opportunity to have DD be able to learn this stuff online! It's so much better (for both of us!) than me trying to work with her out of a text book.
