Hi, Ron... OK. I've made a brief tutorial which is as yet not on public release as there will be additions. It should explain a few things. I'll IM you the link. Any further questions, please ask me and I'll be pleased to enlighten! Except... I'm going away for Easter and will be back on Monday evening (UK that's mid afternoon in the states). I threatened to take the lap-top but my partner told me she'd throw it in the river! As soon as I get back I'll jump straight to this thread! Howard:)
