Alternate stylesheets; default's rules carrying over

[Ben Rogers]

I would like to know if the following is supposed to happen: When I switch to an alternate stylesheet in FireFox (using "alternate stylesheet"- i'm not going to worry about the JS switcher yet.), the rules that I didn't declare in the alternate stylesheet, but are present in the default, carry over. This, obviously, destroys the page's look, and I would very much prefer if it didn't happen.

Can anyone tell me why this is happening to me, or if there's a way to stop it?
