Chart formatting randomly changes on file re-open

A

Angela

I format my charts (font size, color, etc.) in 2007 and then I save and close
the file. When I later re-open the file (later in the day, the next day,
etc.) the chart formats often change; it's pretty random, however, as to
whether some, all, or none of the charts change. Is there a way to prevent
this?
