I just finished reading about Axure RP standard vs RP Pro. The only remaining question I have is related to the integration of the two. Can a mix of both version be used on projects? We may want to have the talented business clients lay out their vision using Axure RP. Then, when the final prototype vision has been agreed to, finalize the documentation. Can a RP Standard file be opened by RP PRO? Conversely, can an RP PRO file be opened by RP Standard? Would it ignore the annotations?
