My experience with CS2 has been that there's no problem with having an earlier version on the sys... the only problem is when you want to use a CS2 brush in the earlier one... mostly, can't be done... there are an enormous number of free brushes and so-on avaliable at Adobe that you can download for 2 or 3... more than for the earlier, LOL... Lou.
