Style bug
Fragment of a discussion from Support/LiquidThreads
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. :)
