Joe,

I am indeed aware of the recalculation issue. Fortunately, the sheet is
mostly for viewing purposes only, summing totals from other worksheets and
workbooks. The recalculation takes mere seconds, however. Strangely, the
alt+shift+ctrl+F9 recalc takes a full minute or more...

I will explore your proposed solution when I've got some spare time.

Are you aware that that causes those functions to be executed every time any
cell in the workbook is modified?

Alternatively, I would be inclined to do the following.

First, create a Workbook_Open event macro. Choose one unused cell in the
workbook, say Z1, and do the following:

Private Sub Workbook_Open()
Range("Z1").Clear
End Sub

(Of course, Z1 does not have to be totally unused. It can be any cell that
Workbook_Open modifies for whatever purpose.)

Then, for each function that you want executed with the workbook is opened,
create a dependency on Z1 either by passing it as an unused parameter or by
including it in the computation, e.g. MarkP(...)+Z1 or MarkP(...)&Z1
depending on the type of the value returned by the function.

Of course, you could accomplish the same thing by having the Workbook_Open
macro directly calculate the cells that contain references to the functions
that you want executed when the workbook is opened; e.g.
Range("B1").Calculate.

The problem with that is: if you move those cells or otherwise cause them
to be moved, Range("B1") might no longer be correct. You can ameliorate
that problem by naming all of the cells and ranges of cells to be executed
when the workbook is opened, and Range("name") in the Workbook_Open macro.

alt+shift+ctrl+F9 worked as well, but bogged down my PC for a full minute
or
two.

The 2007 vs. 2003 issue I described was occuring becuse there's an
additional; option to enable linked content in 2007 that was not being
actived.

My spreadsheet now works exactly as I'd hoped. Thank you!

Also, the formula in the worksheet cell is "=markp($F4,4,454)" in one
case
anyway.

I have many cells using a formula I created in VBA (below).

When the workbook opens it asks me to allow macro, and I do. Then it
asks
if I want to update, and I do. The cells remain un-updated, however,
until I
double-click on them as if to edit, then hit enter. Only then does any
one
cell update.

I have made sure the File-Options-Calculate-Autocalculate option has
been
selected.
F9 has no effect.

Note that the worksheet "Mark P" is hidden in this workbook, and the
values
in Mark P are coming from a worksheet in a different workbook. I have
confirmed that this part is working properly, though.

You help is seincerely appreciated.

Function MarkP(task, start, fin)
hours = 0
For Row = start To fin
Set curCell = Worksheets("Mark P").Cells(Row, 4)
Set valCell = Worksheets("Mark P").Cells(Row, 5)
If curCell.Value = task Then
hours = hours + valCell.Value
End If
Next Row
MarkP = hours

End Function
