I have Office 2003, this started a couple of weeks ago that simple formuls
like Sum or =A1+A2, etc, will not calculate. These are worksheets that work
when I have them open and then a little while later will not work when I open
them again. I can close and not save and then try to open them again and the
formulas will work the next time (sometimes I have to open and close it 4 or
5 times before it works).

It seems to be happening more frequently now.

I checked that autocalculate is checked. Even hitting F9 will not work.

Could be a virus on your computer or in the Excel files.

We have McAfee running constantly. Would uninstalling and re-intalling Excel
help? what do you think?

I'd try reconstructing the calculation dependency tree; press
CTRL+ALT+SHIFT+F9.
Note that Excel has one setting for automatic or manual calculation for all
workbooks open in that instance of Excel. The first workbook opened
determines the setting.

just workaround, to have calculation untill investigation on virus issue

try this code,
go to VBE, double click on "this workbook" and copy this code

the below code forcely makes excel to calcuate whenever you open excel and activate any sheet.

Private Sub Workbook_Open()
Application.Calculation = xlCalculationAutomatic
End Sub

Private Sub Workbook_SheetActivate(ByVal Sh As Object)
Application.Calculation = xlCalculationAutomatic
End Sub


all the best
