We have used CyberDuck to connect to several WebDAV servers for quite a while now and there has never been an issue. We have accounts that have an "@" symbol in the username (people use their e-mail addresses). In the most recent update, 4.1, on both the Windows and Mac versions, If a person enters their username in the quick-connect menu and presses connect they get the following error (windows version but also occurs on OSX):

DNS Error
No such host is known

If the user does NOT enter their username in the quick connect screen and instead waits for the prompt to enter the username and password and they enter in their username with the @ symbol, it connects without a problem.

Again, this worked fine in 4.0. It is preventing us from using CyberDuck in our organization.
