Poma,
Perhaps we have already solved it, what you say? :)
I did respond to John and confirmed that the size parameter he suggested
did exist, but had the value 'normal'
Allen asked for another issue - background/wallpaper,
and still didn't respond about advice offered.
I didn't see a response to that other than logging out and trying other
users. They are OK, this one user is still stuck. Any application that
gets the focus re-draws its part of the screen, but everything else just
stays as it was, even the system menus.
