The screen resolution is normal iPad, 1024 x 768. But on a normal monitor at same screen resolution it is fine. perhaps safai on i{ad takes up more border space or something.
Yes, I can see why the banners would go underneath if there is not enough width, I just thought as the site is fine on 1024 on a laptop or desktop monitor, it would also be fine on iPad. Obviously not.
I think most sites optimised for 1024 Screen res have a max width of 980px, to take into account various different browser margins, I notice that although SOTW is not fixed width, as you reduce the width of the window, the banners go out of whack at about 1000px. The forum is about 924 wide and so there is a fixed margin each side of about 38px. my guess is if these margins were reduced the problem would go away on iPad, not that it's a huge issue, just thought I'd mention it.
