I have a good one for you, and just a day before the end of the world.
Acrobat 9 Pro, 9.4.4.
Double click on a PDF from the desktop and the link button is disabled. In fact, it's disabled for any other PDFs you try to open.
Open Acrobat 9, then double click on the PDF, link button works. (workaround)
This is the strangest thing I've seen in a while. It doesn't happen on other machines with the same version/file.
Anyone want to respond to this one?
