Hi Christopher-

>IDV-1.3a3 has extremely serious problems on Apple's OS X and hardware

We've had others use it on Mac OS-X without these problems.  I'll
get details of the version and graphics card.

Wow, that sounds like a weird OpenGL driver problem.  We've changed nothing
in the code that should make something like this happen if it didn't
happen before.  Is there a way to check the OpenGL settings of
the card?

If you do feel reckless, it would be good to know if this is
a problem with 10.4.3 or your graphics driver.

I would think turning off the machine and unplugging everything and
shutting off the monitor should flush everything out.
