Bill,
Thanks. I think during browsing the 4.2 docs there must be a link which put me back in
the 4.1 doc and so I missed the page which covers this.
By the way, the strip chart options pop-up doesn't contain a "Delete chart ..." entry,
and if I choose "Chart Options" from the popup, the "Data" tab doesn't have an
"Export..." button.
Cheers,
