Thank you very much Rharv and Mac for your replies.

Rharv as regards the render dialog I guess I just liked the idea of having it there as it is in Biab, as it did seem to provide extra options. Thank you for your answers as regards the other points have really helped me.

Thank you very much Mac for your reply too.

I really must try and open the program more often as I find I do forget how to do things easily.

Regards and Thanks again
