I've run into an issue within the last week that for the life of my I can't figure out. Currently, whenever I try to view a PDF file in safari (clicking a link directly to a PDF for example), I end up with a blank page. The weird part is that PDF's that appear in a frame within a page load just fine, but as soon as I right click the PDF and open it in a new tab or window, the resulting tab/window is blank. I can right click the link an download them just fine, and Preview loads all PDF's perfectly, but for whatever reason, a directly linked PDF won't display in Safari. This is all on the latest version of 10.8 and Safari, and I don't have anything installed that would interfere, such as Adobe Reader or Acrobat.
