I'm that guy in the office that always downloads the betas, always been willing to take a risk to try out the newest software, so I've been through a litany of nightmares when it comes to new programs and their inherent bugs. That being said, I have to say that Acrobat Pro 9 has never given me one bit of trouble. I upgraded from 6 to 9 so I could take advantage of the LifeCycle Designer to design forms for my company. Installation went smooth, and it's never given me any trouble. I recently upgraded to Office 2007, and both programs continue to function perfectly, separately and jointly. I always hate to see other have problems with their software (there are just so many better ways to waste time), and everyone is certainly entitled to their own opinion, but I have give this one a thumbs up.
