In two of my computers, Adobe Acrobat Reader (newest version) has this kind of bug: when I open some document, and scroll to some page, then switch tabs (if in browser) or alt-tab to another program, and after some time switch back to Reader, it "forgets" which page I was in, and displays random page, like it scrolls automatically to random place. Tried re-installing, different browsers, different documents, still this problem. If I don't alt-tab, everything is ok. Just when I switch focus to other program, and back again to Adobe Reader, document is scrolled somewhere else than where I left it. Sometimes Reader scrolls to another part of the page I red before, sometimes it jumps 2-3 pages forward. Why is this happening?
Can you please do the following in Reader:
This should do the trick.
