The picture is too large and will be truncated

This is what I get in Excel 97. I searched on the internet and only could
find a MS KB article referring to Office 2000. It also appears that this is
some kind of bug... that has been in the Office suite since 97 and still is
in Office 2003, etc.

I have VBA code copying and pasting text rows. There are no image picture
involved. But when I get this message, I do not get any reference of where
it was in VBA code.

How can one find out more about this bug?
