problems editing an inserted chart

[Bruce]

Word 2002 - I insert a column chart using the menu Insert -
->Picture --> Chart. The chart and the datasheet show up
successfully. However, if I deselect the chart and then
try to edit it by double-clicking on it I get the
following error message: "The object is corrupt or is no
longer available." I've tried this in a number of
different scenarios with no luck. On another PC in my
classroom it works just fine (ie, MS Graph opens).

Thanks,

Bruce
