Style bug

I don't see any problem in either. If you see the sidebar pushed down in monobook, there is a bug for that (it's ok for me in your links, it's not very consistent an error).

In vector skin, the settings area is too small. Perhaps the typography update is the reason.

Ah, probably. I override it in my browser so I don't see a difference there, please report the problem in bugzilla and attach screenshots. As a workaround, my personal suggestion to everyone is to use monobook for the future. :)

I think it's not worthwhile to create a bugzilla account for that. Can you report the bug for me, please?

No I can't, because I don't know what you're seeing exactly. It takes less time to create an account on bugzilla than to reply here that you can't.
