First, I would not rely on what McAfee tech support says.
In the McAfee forums, nobody from McAfee ever owned up to the issue I raised
about deleting files.
A number of experienced McAfee users confirmed the issue.
I would never use McAfee, unless it could be demonstrated that the issue I
raised had gone away, and even then,
why use McAfee when there are better alternatives such as Kaspersky
More importantly, OFFICIALLY, tho MSFT mealy mouths this in KB articles, two
versions of Office are
not FULLY compatible running concurrently. Some folkes do this and face no
problems, but that's just asking for trouble,
especially when dealing with macros.
I've not yet used Office 97, but it would not surprise me if either Excel
2003 or 2007 got unhappy when flip flopping
between versions in the same OS.
