Thanks for checking, Sergey.
I tried later Sunday PM and all was OK
I spent a few hours with Foxcharts and - forgive the mixed metaphor - it's off the chart!
Developers who, like me, haven't been using charts or graphs as part of the development arsenal might want to look at Foxcharts as a way to bring information more meaningfully to the enduser, and to create a new revenue source.

Thanks to the developers and to VFPX.
