'browse host' butten not found

On the limewire webpage it lists a 'browse host' feature that allows you to look for all the shared files on a particular computer. I cannot find any reference to this on the program itself. I do have a copy of the most recent Limewire Pro that I purchased off the website. I am aware of the search 'files on: IP Address:slot # ' but I do not know how to find the slot # for a particular computer once I find their IP address in the downloads window. Is this the only way to activate this feature?

Any help would be appreciated.
