Thanks Joanne. The harmony thing is great. Must play with it some more. I think there are more questions than answers. Cheers.

Thanks Guenter. So much to explore . So many toys to play with. Cheers.

Jan and Bud. Thanks for the lovely comments. People keep telling some of us (well me anyway) to grow up, but hell, what's the rush. I'm only 73. Cheers.
