According to a statement posted on Adobe’s Web site, the company “does not plan to issue updates to current versions of those products for Windows Vista compatibility.”
That means users will have to pay hundreds of dollars to upgrade their Adobe software if they want trouble-free performance on Windows Vista, which is now preinstalled in virtually all new PCs shipping in the United States. That’s because the current versions of most of Adobe’s major products won’t work properly on the new operating system.
I personally have not tried any of the older versions of Photoshop on Vista, so I can't report on any glitches. Anyone else?
Update: Here's an FAQ from Adobe about all of their products' compatibility with Vista.
