I downloaded the latest version recently - 2.6.1 (2376) - and every upload since then, all to sites I have previously sent stuffed folders to succesfully has disconnected and shown the following error message I/0 Error: Broken pipe. I read the list of fixes on the latest upgrade of Cyberduck before downloading and recall that pipe errors were one of the things the upgrade would fix (am I recalling this correctly?) - why is this happening to me now on this version when it didn't on earlier models?
Look forward to your response.
thanks,
Neil
