Ok, I figured it out....
In my situation all the offending text in the IV title block had the
"Spacing" set as "Exactly" in the Edit Definition dialog box.
It should be "Single". That fixes the problem.
I don't know why IV chose to create the text with "Exact" spacing unless it
just happened to be selected while I was making my text for the title block.
Something to look out for when editing title blocks.
