Like others who have commented here, I have been a very happy Paperport 9 Professional user for several years. Last month, when I got a new high-end laptop with Windows XP Pro and saw that Paperport 10 Pro had just been released, I checked it out and was excited about all the new features.However, from the moment I loaded it on my computer (and I should note that I am a VERY experienced computer user AND I actually read and follow directions carefully - so this isn't a case of some newbie who didn't know what he was doing) this software has been an unmitigated disaster! Everything ran at the speed of stone and my system crashed repeatedly. In the end, I completely re-imaged my computer back to the way it was when it came from the factory and re-installed all my software. I went back to Paperport 9 Pro and everything is fine again.BUYER BEWARE !!
