Automatic/Manual Calculation

[Scott D]

Sometimes, when I open a workbook, the calculation setting has been changed
from automatic to manual. I have never in my life change this setting. It
seems to be more prevalent after I use microsoft update. I also have to
manually fix the DDE settings after an update because I can no longer open
my files by clicking on them from my desktop until I use the "%1" trick in
the file preferences area. Any thoughts?

Tools>Options>Calculation 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>

For the DDE settings it may be easier to just re-register Excel

Close Excel first and On the Windows Taskbar

1) Start>Run "excel.exe /unregserver"(no quotes)>OK.
2) Start>Run "excel.exe /regserver"(no quotes)>OK.

See the space between exe and /regserver

You might have to designate a full path to excel.exe.

In that case Start>Run "C:\yourpath\excel.exe" /regserver(quotes
required)>OK.
