I read the post. It seemed to talk about de-bugging and nothing about my question. I am a single individual user that only uses Photoshop 5-6 times a year. Purchasing the Pro Edition, and it's yearly $99.99 ball and chain, does not make financial sense for me if Parallels Desktop will do the job. The VM will be Windows XP. Do I need Visual Studio Pro in order to run Photoshop CS3? Or, will Parallels Desktop allow me to run CS3? Thanks, Tim
