This warning occurs when creating a pfWindow. Why you get this warning
when loading a obj file is not exactly obvious to the naked eye :)
Seriously though, you may want to run your application against the debug
version of the obj loader (and maybe libpfdb-util) and step through it to
find out which pf call exactly is causing the warning to get generated.
Once we know this then we'll be able to dig a bit deeper.
At first glance, there doesn't seem to be any windowing code in the obj
loader so I don't see what would cause this warning to get generated. (and
that would be pretty odd for a loader, in any case.) Can you try calling
pfPipeWindow::open() before loading the files to see what happens? (just
for kicks ...)
A+,
Alex.
