Right now we have two users with Fireworks CS4 and one user with Fireworks 8. The problem is that when the CS4 users open up a fireworks 8 file, they are prompted to maintain appearance or update text. So we are going to upgrade the fireworks 8 user.
If that user gets Fireworks CS5, will we have a similar problem between CS4 and CS5 versions? Or are the file formats identical\fully compatible?
