This had all the promise of what I wanted - a quick and easy way to make simple mark ups of screens, documents, emails, etc to send back. Unfortunately it fails in virtually all respects, to the extent it does not crash, it fails to 'work' on half my programs (eg will make no notations whatever) and for those in which it will make notations (for example on a reply email), the actual email does not have the markings - only the screen does! Text appears virtually at random and can not be moved. If there are 'solutions' to these problems they are completely non-intuitive. I don't have time to work around what seems to be a complete kluge. Save your money and look elsewhere. I would give it a lower score if I could. Now I trash it and move on. M
