As of today and after the latest update, Cyberduck is not working anymore.
It loads first normal, then let's say I want to upload some files, I choose the DIR where files have to be.
Then I choose the files in my local machine and THEN ... NOTHING HAPPENS
The Cyberduck window becomes unresponsive and has to be shutdowned with Ctrl+Alt+Del.
Reactivating the progam doesn't work (window appears only for a fraction of a second).

The machine has to be restarted in order to get cyberduck back.
But then all over again the same problem.

Thank you for your advise.
