Might I suggest, where you have the choice, you use something other than Adobe for PDF reading? There are a number of free alternatives. I have
Acrobat x on-board but disabled for file association because it's far from the best, IMO. Your little glitch being just one example.
Foxit PDF Editor is what I am currently using and it's a wonder for it's ease and power with PDF files.
There are a variety of 100% free things like Nitro as well. I'd say just about all the major ones have more features.
