I've been following the threads on Wine HQ. Someone claims to got it to load, but no details how or what he did. He did state that it crashed shortly thereafter before he was able to bring anything up. Later on this year, I believe Macromedia will start working on another version of Dreamweaver. I don't know for sure. But the beta applications have already been posted.
I tried running the program that validates/registers the program by itself before running Dreamweaver. Needless to say, it didn't work.
