I have a workbook that works fine in excel 2002, but runs extremely slow in
Excel 2003. For example, one macro which is fairly complicated but doesn't
process a lot of sheets or a lot of cells, takes about 10 seconds in 2002 on
a PII-350 with 128 mb RAM and Win 98SE, and takes about 10 minutes in 2003 on
a AMD Athlon 3200+ with 512 MB RAM and XP SP2.

The following code is a stripped down version of the macro in question. It
takes 4 minutes to run.

Option Explicit
Private Sub worksheet_activate()
Dim M As Long
With Me
For M = 1 To 8
.Columns(M).ClearContents
Next M
.Cells(10, 3) = "Tax Report"
.Cells(1, 1) = "3. Mutual fund units, deferral of " _
& "eligible small business corporation shares," _
& " and other shares including "
.Cells(2, 1) = "publicly traded shares"
.Cells(4, 1) = "Number"
.Cells(4, 2) = "Name & Class"
.Cells(4, 4) = "Yr Acq"
.Cells(4, 5) = "Proceeds"
.Cells(4, 6) = "Cost Base"
.Cells(4, 7) = "Expenses"
.Cells(4, 8) = "Gain (Loss)"
End With
End Sub

This is a new install of Office 2003, so I'm wondering if something is not
set up properly. Anybody have any ideas?
