Weird bubble chart problem:

Using excel 007, I'm having trouble with what used to be the chart
wizard when I try to create a bubble chart.

I've set it up with X, Y, and Z columns and 50 (state) data points
with variable labels in the first row.

When I highlight all that and insert a bubble chart it does not seem
to recognize that the first row are the series names. The data
selection shows no series name and the data ranges start with the
label cells.

Oddly, it works fine if I only highlight 14 rows (13 states).
Anything more and it goes bust.
Indiana messes me up everytime. I've checked for non-numeric data
cells, there are none.

I can do it with 13 datapoints and then stretch the matrix down to
make it work.

But it's not supposed to work like that. If I were a Canadian, I
wouldn't complain....
