This same problem has been happening to me as well ever since I switched over
to 2007 last spring. As with others, it is more than a bit frustrating when
the actual names are relied on and then get switched back to default Chart 1,
Chart 2, etc. Isn't there any MVP out there that can get MS to look into
this?

I making a workbook that will have approx. 130 charts and name each tab as I
go. Yesterday, I finished up number 68 and this morn I opened the workbook
and found that ALL the tabs have converted to numerals! What would cause
that? I depended on the tab names to inform me of alignment of data.
