When launching Fold.it client, when using multiple clients, only the primary (first in) client can have live chat and receive new recipe downloads. Use a graphic to show that if Fold.it client is primary or not. I suggest using a chain link graphic in Chat area.

If chat is not live, the only way of continuing to use client and chat is through the use of IRC and downloading new recipes cannot be done at all. These shortcomings are not obvious when you first launch client and the only way to know if this is the case is to test. A graphic chain link would save time and avoid frustrations.
