I've used DockFun for quite some time (and have it licensed for 10 cpu's). There have been few updates. No support email address. Occasionally DockFun starts consuming extra CPU, you have to quit and relaunch. No updates for Leopard, no updates since 2006. If you are a Tiger user and don't mind it sucking 30% CPU cycles when it burps its fine but the lack of support and updates have me looking for a replacement. Unfortunately I can no longer recommend it.
