Illegal Operation in Excel

[Scott]

After I make a coupl of changes to an Excel document I get the following error:
(Win98SE machine, Office 97 ...)

this program has performed an illegal operation and will be shut down.
if the problem persists, contact the program
vendor.

EXCEL caused an invalid page fault in
module MSO97.DLL at 0187:306c2669.
