To clear up some possible confusions:

when Excel calculates (F9 or Application.calculate or Calculation is
Automatic) it calculates all open workbooks not just the active book. (there
is no option in Excel to only calculate the active workbook)

Calculation settings like calculation=automatic/manual are set at
application level rather than workbook level (if calculation is manual it is
manual for all the open workbooks), and the setting is controlled by the
first workbook opened until you change it through Excel Options or VBA.

Normally Excel will only calculate things that have changed and formulae
that depend on things that have changed, but you can force a complete
calculation of all formulae in all open workbooks by pressing Ctrl Alt F9
(all at once).

Sometimes Excel gets it dependency trees messed up in a particular workbook
and this may cause a recalculation to not work properly: pressing Ctrl Alt
Shift F9 (all at once) will rebuild the dependency trees and do a full
calculate.

Other possible sources of problems a
- not being in automatic calculation mode when you think you are
- visual basic User defined functions
- circular references
- calculation being interrupted by something external to Excel

Hi,

My earlier threads might just be symphtoms of the workbooks unwillingness
to calculate.

LINKS DOESN'T RECALCULATE
If I change a value in Sheet10, it's link in sheet11 doesn't recalculate.
It does only recaculate if I force a sheet10.calculate and
sheet11.calculate or run application.calculate (but I have a lot of links
and sheets, that will take to much time to do in a user perspective)

TEST WITH A NEW EMPTY WB
If I start a new empty workbook and make ONE single link between sheet1
and sheet2, the sheet2 value will recalculate VERY SLOWLY - (4 seconds,
seeing the 10...30...50% in the bottom of the application) when I change
the value in sheet1.

TEST WHIT/WITHOUT MY WB
If I close my workbook excelfile, the new workbook with only one link will
work o.k. again. If I start the workbook excelfile, the slow calculation
starts again in the New Empty "one link workbook".

Even if I take away all startcode in ThisWorkbook the probelm remain.

It doesn't change even if I restart excel. I have Excel 2003 SP1 running
on windows xp sp2 and computer is 3 Ghz and 1,5 GB RAM ...

Pleeease bring light in this mess ...!
