Im like greased lightening
However - I can not reproduce the error your talking about. The only annoying thing for me is that my article header image popup isnt wide enough (going off to sort it now)
As far as Im concerned - this things about ready to go live (unless you can find any other reason not to).
BTW: I still havent gotten any feedback on upgrading from Gas3. Maybe ill pop over to that thread and find out.
