Need help with a Datagrid error...

I should have noted the LC version. This is a standalone built under
LiveCode 6.7.11

If I could get one of the customers to respond with their document(s)
and settings that caused the error, it would probably be simple to track
down.

My current theory is that rows can display either htmlText or an image
in a particular column depending upon the users data. I am speculating
that an image may not be being resolved correctly. This may just have to
wait until a customer cares enough to help us troubleshoot it by letting
us look at their data.

It was a wild shot that someone else may have recognized this. Thanks
for replying.
