Actually, I believe now that my problem is not where I was looking for
it.

Remember that I want any .xls that is openned to be re-calculated once.
By putting the SUB Workbook_open procedure in my .xla I was effectively
telling Excel to recalculate only when the application openned (and
hence the add-in workbook openned too).

So, I now wonder: how do I put something in an add-in that will trap
the event of an .xls being openned? I guess that the
Application.WorkbookOpen event will be what I need.

Thanks for the help though!

Hi Brian,

try this

Dim oSht as worksheet
Application.Calculation=xlCalculationManual

for each oSht in Worksheets
oSht.enablecalculation=false
osht.enablecalculation=true
next osht

Application.calculate

No, that does not 'force' my sheet to recalculate. From xl2000 on there is
Application.CalculateFull, but my understanding is that CTRL-ALT-F9 is
equivalent in xl97

Not sure if you can use the following in xl97 ?

Private Sub Workbook_Open()
Application.Calculate
End Sub
