Following is a good article on Adobe problems. I would stay away from Adobe if you can prevent it. There are many other good readers. Adobe's problems aren't worth the aggrevation. Believe me, I've been there.
I love where the article says:
"Does anyone besides me think that anything that continues to have so many things to fix each quarter, month, or whatever the interval is chosen, is not very well written?"
So, does that mean we better ditch all forms of the Windows OS?
That statement alone takes away the authors credibility in my book.
(and by the way, I have very little issues with Reader nor any other product of Adobe)
