I installed the latest Office 2003 updates around 25 July 2007.

I now see that, e.g., XIRR is no longer available.

If I fiddle around and use the Add-Ins menu, I sometimes, but not always,
get the XIRR, and other functions back, but ONLY while the workbook is open.

Even tho the Add-Ins remain checked, when I next open a workbook, the XIRR
is gone.

Either due to a bug in the update I downloaded, or somebody snuck in a not
so cool virus.

Any other reports of this problem?
How to fix?
