[reportlab-users] Fwd: text of paragraph sits at bottom of area.

[Kerri Reno]

Thank you Tim and Robin for your help.  That's exactly what I needed.  I
didn't know that wrapOn returned the size of the paragraph, so I was worried
that I'd have to somehow calculate it myself, and I didn't have a clue how
to do that.

Thanks again!
Kerri
