Common problem......not yet fixed in 2007 version.

ToolsOptionsCalculation can be Auto or Manual.

Excel takes the Calculation mode each session from the settings on the first
workbook opened in that session.

i.e. If you saved Book1 with calc mode in manual and opened it first, calc
mode would be in Manual.

If you saved Book2 with calc mode in auto and opened it after Book1, Book2
would be in manual mode(Excel ignores the auto calc mode in this case).

If you close Book1 before opening Book2, Book2 will be in auto calc mode.

Confusing enough? <g

If you want a particular workbook to always open in AutoCalc mode you can use
code to set it to auto whenever you open the workbook.

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

Right-click on the Excel Icon left of "File" and select "View Code"

Paste the above into that module and save the workbook.
