This still seems to be a problem with 2.0. I'm also now seeing many "tradj 
error" messages in the window.

I get no errors with text, but do get the tradj error.  This error
report has probably been around a while though, possible a case of a
problem with the input data.

Also,
1) osgcatch crashes on exit

Any chance of stack trace?

2) osgforest seems to have black lettering when it initially appears. Using the 
right arrow 3 times or the left arrow once turns the text to white. I'm not 
sure if this is by design or not.

Its not be design, and is a bug that I can reproduce at this end.  I
don't know why the state is bleeding into the HUD text.

3) osglauncher crashes at various times before or after launching the 
subprogram.

osglaunch runs fine on my linux system.  If there are problems it may
well be down to a bug in window manager not able to handle multiple
OpenGL windows properly,

I'm running on Linux with an NVIDIA Quadro GX 4400.

Could you provide more details.  I.e. linux version, gcc version,
driver version, hardware configuration.

Also, while I'm here, how do I configure cmake/GNUmake to have 
-DCOMPILE_USING_TWO_PARAM_sched_setaffinity=yes when I compile OpenThreads?

Arggg, did you not try the OSG SVN/1.9.x build at all in the last two
months? This type of issue is real issue to catch if its gets
reported.  Pretty frustrating that only after 2.0 gets tagged that the
code gets tests and problem reported.

I presume you must be using a RedHat or other distribution with
similarly non standard kernel. It should be possible to add the
-DCOMPILE_USING_TWO_PARAM_sched_setaffinity=yes via CMake, for
instance via the CMAKE_CXX_FLAGS variable that you can set when you
run 'ccmake .' and then press 't' to get the advanced options.

A permanent solution will be to modify the OpenThreads CMakeLists.txt
to provide the option to configure this variable directly, or perhaps
even detect the non standard kernel API and add the -D in
automatically.
