Certain Adobe Systems software, including Creative Suite 2, Serious Magic software, Macromedia Studio, and any Adobe products made available on or after Jan. 30, may not work properly with the Windows Vista operating system.

In an FAQ on its Web site, Adobe indicates that the above-mentioned products, as well as Photoshop, InDesign and Dreamweaver, have compatibility issues with the Windows Vista.

For example, Adobe Photoshop CS2 calls for users to register the software every time it is launched on a Windows Vista PC, even if the software has already been registered by the user.
