Well it seems to depend. With smaller less complex formulas/workbooks, it
seems to work okay, but as the complexity increases, the odds of the F9 key
working properly decreases. There has been numerous times in the past when
I have attempted to use the F9 key to calculate only to find that it didn't
calculate all the way through, so when MS came out with the Alt-Ctrl-F9 to
address this issue in Excel 2000, this made my life so much easier to work
with. I even tested the F9 in XL2000, and it still didn't work properly for
me, but then I have more complex worksheets and workbooks too.

For the set of workbooks that I have a huge number of calculations, they are
in an instance of Excel to themselves with the calculation mode set to
Manual, while other workbooks with limited number of calculations are in a
separate instance of Excel with the calculation mode set to Automatic. I
typically have 2 or 3 difference instances of Excel up on the computer at
one time unless I am testing things out that may need to be proven it's not
just a system resource issue.

F9 may or may not work. I have had too many issues of F9 not working
properly as it was intended to work. Shift-F9 (Sheet level) or
Alt-Ctrl-F9 (Forced full calculation) does work. This last one has more
or less replaced the F9 key as it makes sure everything gets calculated.

First of all, replace the formula with

=SUM(B2:D2)

however that won't affect your problem but you should not use SUM in the
way you used it so either B2+C2+D2 or the simpler SUM(B2:D2). What
happens if you press F9?

The formulas that I have put into the program, Example: =sum(b2+c2+d2)
is not
adding my numbers up in the designated cells. It is like the program
has been
contaminated or locked up some how. All my files that I use excel with
are
not responding.
