As long as you are on a 24-bit display and you
are reasonably careful about colors (you may have
to load your color table before you draw graphics
in some circumstances, etc.), there is no problem
running both direct graphics and object graphics
windows simultaneously. I do it almost transparently
all the time.

Well, I'm pretty sure I didn't say *that*. I think
I said I am finding more and more reasons to use
object graphics, since often the advantages of doing
so outweighs the drawbacks. But you do have to carefully
weigh your options for each project. There are some things
that simply can't be done *without* object graphics. In
those cases, I'm always thrilled to have them. :-)

Cheers,

David
