I logged in with another user, and tried to edit the class, and was told it was locked. This didn't seem right since I hit the "store" button multiple times when I created it.
On a hunch, I went back in under the original user with Internet Explorer instead of Mozilla Firebird. Sure enough, the "store" button published the changes. Apparently there's a glitch with using Firebird for that form.
Also, the stylesheets don't work right in Firebird either. This is very much an IE-only app.
It seems to be random as to whether pressing "store" from the class editor screen will actually store the class. I've pressed "store" a million times, but the new fields are not appearing on the object editor, and when I log in under another user account and try to edit the class, I get a message that the class is locked by the first user.
What's the trick to actualy storing these class changes?
