When creating a large number (120) of pie charts on a worksheet I
unexpectedly got a warning message about half way through saying something
like 'No new fonts may be created in this workbook', and an OK button.
(Office Student & Teacher 2003 version of Excel)

Clicking OK (at least once) allowed me to continue but the message appeared
every time I wanted to create and then edit another chart on that and
subsequent worksheets in the workbook.

I'm guessing that the message was related to the large number of charts
being created? Anyone know if that's true and, if so, how to create a large
number of charts on a single worksheet WITHOUT getting the warning.
