I am running Snow Leopard on a Macbook. I have the most recent version of Cyberduck. I am able to connect to the ftp and see a file list. My downloads default to the desktop. When I attempt to download a folder, there is no progressive status in the bottom left corner of the browser window, but an empty folder with the correct title appears on the desktop. Please help.

Thank you,
Brandon Rees

I have the same issue. Dragging a folder from Cyberduck to a Finder window gives me the correct folder, but only containing another empty folder. I tried with another folder without subdirs and then I just get an empty folder with the right name. Basically I cannot use Cyberduck to manage my FTP sites at all with this version...

Best regards
Seph

Can you find any related output in the system.log (/Applications/Utilities/Console.app)?

So far I've found that if I want to download the contents of the folder, I have to click Resume on the transfers window once for each file in it. If there are nested files, I have to click resume for each folder, then for each file inside those folders again.

Console output is:

Should be fixed in the latest nightly build.

In the latest nightly build, this problem still exists for me. This system is not allowing me to change the status of this problem, but it HAS NOT BEEN FIXED for me. Console output:

Thank you very much for the great program, it's working fine now. I'd really missed being able to work with Cyberduck.
