It is fixed in 4.0.

I want to tread lightly here: I work for Rogue Wave. I have an email
address. But I don't work for Rogue Wave while I'm reading email (and
vice versa). And I want to avoid any commercial use of this posting.
However, for the sake of *information only* I would like to make clear
that M. Flower's statement about the availability of version 4.0 is
correct. Folk should be able to contact Rogue Wave about upgrades:

Rogue Wave Software
1325 NW 9th St
Corvallis OR, 97330 USA
(503) 754 2311

Still treading lightly: If you are a user of the library, and have
not sent in your registration, it will be hard for the folk at
Rogue Wave to justify giving you a "current user's price". Of course
it is never too late... Word to the wise, eh?

If you wish to assume that I will correctly handle email for Rogue
Wave, you may use my address. I make *no* guarantees with respect
to speed or accuracy, but I will attempt to do the right thing. As
and when it is convenient. For me.
