If you want to work on an ideal implementation, I'd welcome

Okay, thanks for the explanation.

What do you think would be the best approach here? I think a
read-only text control might be best, despite those issues,
because someday I'd like to add some more fields that really
ought to be read-only but copyable. For instance, it'd be
nice to have a field indicating when and by whom an entity's
contents were last modified. If it seems to have the wrong
value, I can reply thus to an error report from a user:
  "You said the policy fee is $5, but in my copy I see the
  correct value, $3, last updated 2008-02-03T12:34Z. What
  does the last-modified-date field on your copy say? (You
  can copy it and paste it.)"
Sure, I could ask for a screenshot, but experience shows
that I might get a half-megabyte BMP, or a huge PDF. And if
one information-bearing read-only control is copyable, then
it's probably good to use the same control type for others.
