Dreamweaver CS4 Not Remembering Logon Credentials

Hello all,

I use Dreamweaver CS4 (Mac) and I have around 10 sites I manage. For some reason DW remembers the logon credentials for some sites but not others. Certain sites I will have to go into the settings for them and enter the username and password every time before I can make my SFTP connection.

I searched Google many times, Adobe's support site and tried all the remedies I could find, but none have worked so far. I've searched the MR forums too and haven't found anything related to this particular problem either.

Has anyone else had a similar issue or could assist me?

Thanks!
