Question
After May 2016 update, my Adobe Acrobat XI became extremely slow to load each page that is almost unusable.
I did everything I could including uninstalling and re-installing the program. After initial re-install, it was ok, However, I had the 2-3 year old program with all patches and security updates, etc. missing. The minute that May 2016 update was installed, the program got slow again. I have other computers with lower versions of Acrobat that they seemed not be affected with this issue.
