So I just got my new Macbook Pro and everything works perfect so far (knock on wood). However I just discovered a strange problem when trying to scroll in Preview with multipage pdfs. I couldn't scroll between pages at all, it just flashes to random pages and then returns to the first page in the document. And even stranger it only seems to happen in preview and nothing else (Firefox, Safari, Adobe, Word etc all scroll fine). Anybody have any idea what might be going on?
