I did not add any links.
Yet suddenly, I started getting messages about a data source link.

The link was to ATPVBAEN.XLA.
I use a lot of XIRR functions but never before had the link.

I broke the link and there does not seem to be any ill effect.

What could have caused the link to be added?

There's over 100 XIRR functions in the workbook.

I found 2 that get broken when I remove the link.

All others are fine.

I've saved a copy of the workbook that has the link.
What can I look for to detect the cause?
