I'm trying to format borders in a table and the error messge "The measurement
must be between 1 pt and 31 pt" appears.

I've changed the pt size to 1 pt but it doesn't help. It's only in this one
document. If I cut and paste to a new document the borders function works
fine. Unfortunately, it's a huge document and I can't copy the whole thing
to a new document. Anyone have experience or a solution with this?
