Cyberduck stuck on 'control connection'

cf7497a created the issue

Whenever I try to download or upload a file (e.g. by saving in the associated editor) to an FTP site, Cyberduck remains stuck for minutes on 'Control connection...' (or something like that, I have the message in Italian), then finally performs the operation. This totally disrupts the usage for remote development.

It started doing this today, in conjunction with a version update and also a change of ISP, so it might be something my ISP is doing with FTP connections. However, I have used a command line ftp program from MacOSX's Terminal and it works beautifully, so Cyberduck has something to do with it.

I have no problem with SFTP connections. Unfortunately I do not have other FTP connections so I can't check whether it's the remote server or the FTP protocol.

Mac OS X 10.4.11, Cyberduck 3470.
