The page resizing is back.I've not changed anything. But great that its now working.
A box opens to the right of the top toolbar (causing iPad Safari to shrink the page view to accommodate it in the width of the display), and then the box disappears again (it may get moved somewhere else "on page"; the page then returns to normal scale) almost instantly. This may have something to do with the specific advert banner at the bottom of the page (whatever it is, it renders last), but it is only the main forum listing page that is affected and the sub-listings also carry advert banners, and the main page is affected most of the time.
