Quote - I cannot confirm, that Poser 7 and later doesn't work with DAZ figures.
I am using them with PoserPro 2010 without any problems. The figures have originally been
installed to my Poser 6 runtime which is connected to PoserPro.

I think there were some issues with some new DAZ figures or morps (kids & S4) using scaling.
But those are working in Poser 8 and Pro2010 as well...

So, it looks like your problems are not directly related to the DAZ figures but something else.
Maybe it's some security setting, maybe the graphics driver, maybe some other hardware...
 

The first tech had me change my setting from OpenGL  using ATI Radeon 4800 display adapter to sreeD.  I don't see any difference.  And he had me turn off export binary morph targets because of the v4.2 problem.  He said the Kids4 just didn't work with Poser 8.  With Windows 7, I can[t load a zipped program into runtime of Poser 8.  Also can't modify a texture map and save it back into the Poser folders.  It is a personal computer, I am the administrator and it say I need my permission.  With a dual 64 bit system I should go to PP 2010.  I had Poser 4 Pro, have the disk and can't find the serial number.  They can't help because their records only go back to 2005.  I still have a computer using Windows 98 for an old DOS financial program.  It is so simple.

Great art is simple; but, simplicity requires the greatest art!
