I believe that (since 6.1B4) the popup to pick the page layout looks "bad" (screenshot attached). I suppose that this problem might be as obvious on smaller screen with less screen resolution.
- the radio buttons are detached from the layout label
- the layout label is wrapped even though there should be enough room the keep it on a single line
I'm not sure if this is a regression bug ... I don't remember having had these "issues" with beta3 but will double-check.
