Hello people, could someone here with late 2009 mac mini open the following pdf file? Just how smooth is the scrolling of the pdf file in preview? http://www.freepatentsonline.com/4270766.pdf I am using late 2009 2.53ghz 4gig ram mac mini and the above pdf file scrolls very slowly. Not sure why this happens. The pdf file is just a patent files so nothing to worry about. Just need someone to confirm that im not alone facing this issue. Thank.
