Many thanks for the explanation, and for your link. I've sent you my details, so I'll go through your tutorials.
So how would I implement it so that I can have a single module, and have that set up the widgets so that they can be used independently? At the moment I have implemented it as 2 separate modules, but as we get more and more modules this is going to get quite large, and a lot of duplicated code for the server (rpc) calls. Maybe your tutorials tell me this, If so then great. I'll get there..... Many thanks.
