SP3 bugs ? (Office 2000)

[George Eberle]

We discovered that applying SP3 breaks a Access 2000 database. If we
uninstall Office 2000, and SP3, then reinstall MS Office 2000 with no SP, the
issue goes away.

Specifically, error is:"his expression is typed incorrectly or it is too
complex to be calculated" pops up in Access when a user does data entry in an
existing database.

After clicking out of that error another comes up: "object invalid or no
longer set".

Are there known issues with SP3 and perhaps a patch to apply?

Thanks,
