Hi,

I have a bug I'm trying to find in a fairly complicated piece of software.

I'm hoping if I report the symptoms I can get some pointers about where
to look for the problem.

This problem occurs in both single-processor and multi-processor modes.
Occurs if I use just one pipe or several pipes. Occurs if I use just one
window and channel, or several windows and channels. Occurs if I run on
an Octane or an Onyx. It's always there. Everything is running IRIX
6.5.7f and Performer 2.2.7.

In its simplest form I load two objects with pfdLoadFile. No matter how
I orient the two objects or my viewing position, one object is always
displayed in front of the other.

If I dump the scene and load it in perfly, the objects occlude as
expected.

I realize that this is sort of vague- all I'm hoping for are some general
pointers about what to look for- what types of things could cause this
behavior.

Thanks,

-John
