Help: Links Opening in FTP Program

[Flanders]

Recently, my iMac has developed an annoying habit of opening links from applications such as Mail.app in CyberDuck rather than Safari, even links from Dashboard are opening in CyberDuck.

I've tried hunting through the application preferences but I can't seem to find anything to stop this happening. At the moment I'm resorting to right-clicking and copying the link manually.

Any help would be greatly appreciated.

Thanks Nick. CyberDuck is not open when this happens, for example when clicking on a link from an email, CyberDuck will launch and try and connect to the URL.
