PoseRay is still crashing whith any contemporary ATI graphics card and 
model geometry above approx. 15 MB!
After getting frustrated about using Blender as converter (I really 
loved PoseRay for that purpose!) I did some research and used the 
VisualStudio debugging tools and finally found (at least a temporary) 
The access violation happens within the atioglxx.dll module and it seems 
there is a function call with an uninitialized pointer. NVidia and *old* 
ATI drivers are obviously more forgiving about this issue but 
contemporary ATI drivers are not. As this is not a driver bug it is not 
to be expected that any future update of the ATI OpenGL graphics drivers 
will fix the problem.
But if it happens that you own a ATI card (and its installation CD) from 
2004 (anything newer will not work) you can do the following:

Search the installation CD for the file atioglxx.dl_   (<- note the 

Copy this file into the PoseRay installation directory.

Run a console window and navigate to the PoseRay installation directory.
(e.g. "cd C:\CGI\PoseRay"). If you are using Vista or 7 and PoseRay is 
installed within the "Program Files" folder you will need also 
administrator rights.

Enter "expand atioglxx.dl_ atioglxx.dll".

PoseRay should work again. This will in no way mess up your graphics 
driver/OpenGL installation as *only* PoseRay is effected.

Note that any catalyst drivers from the ATI update side (going back to 
2008) are still too *new* and will not work.

Well, just in case you have no old driver cd available, you may want to 
send me a mail...
