I'm trying to copy and paste a chart in an excel file and when I do this and
try and edit the chart with new source data a window pops up telling that I
cannot add new fonts to excel and then excel crashes on me.

Has anyone ever had a problem like this or knows how to fix a problem like
this?

please respond or e-mail me at
