When I saw the ads for L4, I understood it was an upgrade. I never read anywhere where it would not print, L3 resources won't always work or be auto available in L4, that you'd lose all the menu controls in L3 (Where is my Account Summary page?). How do you find out if all your purchased books in L3 are in L4?
I mean, sure it does neat stuff, but why would I "upgrade" to find out I have to keep my old version at the same time because the NEW version doesn't do the same things?
I'm very disappointed.
