Unfortunately Article KB919127 is badly written, confusing and unhelpful.
The Title talks about Calculate, but the body of the article talks about
Worksheet.Calculate, and further information refers you to an article that
has nothing whatsoever to do with calculation!
There is no statement that Microsoft has confirmed this to be a problem with
Excel 2002 and 2003 (2007?)
Whilst it is impossible to know exactly how inaccurate the article is, or
what circumstances cause the described problem, or indeed what the problem
really is, my best guess is as follows:
- Sounds like there may be a problem with Worksheet.Calculate rather than
Calculate.
- I have used Worksheet.Calculate on many extremely complex workbooks
without meeting the described problem: if the described problem does indeed
exist it is probably very rare.
