Matt,
in my FF3.0.10 both boxes "move". The issue here seems to be the browser
handling the focus and also scrolling into view. We've looked at it, but
there seems to be no way of forcing the browser leave things as they are
when setting the focus to a widget. E.g. there is no alterantive css
'overflow' value to be used here.
The only thing I could think of is letting go of the native "focusable"
property, and implement your own onClick handler that also changes
appearance and stuff, so you get all the behaviour you want, but without
the browser focus.
HTH,
Thomas
