This has no doubt already been brought up a few zillion times, so just steer me to the appropriate thread(s), thanks. Searches aren't exactly my strong point. I'm looking for a (preferably lightweight) substitute for the Acrobat reader, since Secunia isn't happy with my rather antique version. Don't need any more than a reader, and it doesn't even have to be browser-integrated since most of the PDF's I'm concerned with I've saved for ongoing reference. Many thanks.
