It occurred to me after I sent that last, that you can go to the
properties window in VBE for the textbox and set the wordwrap value
to 'true' as the standard  setting in a userform. Note, however, that
I think you have to set the Multiline to TRUE before the wordwrap can
work.
The only other version of a 'standard textbox' that I could think of
is an inputbox, and I don't know how to set that to do wordwrap, but
since it scrolls from right to left, I couldn't see how that would be
needed. I don't know for sure about that, though.
