Thanks for that Charlie,
sorry it's taken so long to reply, sometimes, as I think I've said before, life gets in the way and the fun stuff has to take a backseat for a bit. Rest assured, I'm grateful for any and all of the advice I get and eventually get the chance to put it all into practice.

Maybe it's just me but I find a few things I would think might be pretty straight forward can be more difficult to do than I would have thought, not intuitive, or taking far more steps than I would have thought, not just Biab but other software as well. I do wonder if in some instances I'm expecting too much from a product and developers but I must say in most cases someone out there on the various forums has found a solution or at least a workaround.

Thanks again for you response and assistance.

Andy
