You have program installed in your machine (The program version showing in your software's page
list is now older. The latest is 9.1.0, which you can update either by clicking check for
update button under the Help menu of your program or by downloading and in-stalling it from
www.adobe.com)
Sorry but I have to disagree with that statement. I realize that Adobe was one of the primary
(or perhaps the primary) with PDF files but it has gotten entirely too large and too slow to
compete with some of the other PDF readers that are available (and for the same price i.e.
freeware). To name a couple you can look at and use Foxit or PDF Xchange to get readers (PDFX
has a "sticky note" option as a plus) that are smaller in size, use a smaller footprint and are
faster in loading. Take a look at the reviews for these programs and judge for yourself. Try
them, you may like them.
