B 2.5 Alpha Zoom problem ?

I don’t know if it’s a bug or not, that’s why i’m posting here.
In the properties window, when you choose vertical Align (RMC>crossbox)
the zoom in/out just do it vertically and not horizontally
is that the way it is supposed to work or is there a problem ???

There’s also this message in the console :
Error, region type missing in - name:"", id:16
don’t know if this has something to do with the first problem ?
