I'm semi-literate when it comes to computers. I have all the Adobe stuff. I have no clue what's causing this, but since I updated Adobe & Acrobat Reader, my computer has been acting funky. I can't open a pdf online - it saves it to my desktop; then I can open it. Which is better than not being able to open it at all, which is what happened before I uninstalled & reinstalled Adobe.
Sorry about going so far off topic...
