I've been having issues with this for a long time. Just to make sure everyone understands, I think the OP (and myself) are talking about viewing BGG.com using Safari on iPad. When loading a page (seems like any page), you'll get enough to fill the screen, then it just stops. Sometimes I have to refresh a few times to get the full page to load.
I get that on my iPhone sometimes too. Changing orientation often fixes it; still annoying though.
