I'm having the same problem, running 10.4.11 on Intel-iMac with DW-6.1 -- it crashes DW with "passive FTP" unchecked, and with it checked there is a message saying that it cannot determine the server's "time" so it can't do synchronizing. I can FTP a file to the server with Fetch, and for years with DW-6.1 on my G4 the site-synchronization worked fine, so I guess it's something about the Intel-Mac/Rosetta/DW6.1 mix that's the problem. Is there a solution? Craig
