I've tried both SreeD and OpenGL and both react the same.
Sr3 is installed.
Updated the drivers.
Removed Quicktime.
Done a virus and adware scan.
Cleaned out the junk and registry.
None of these has helped the problem.
I can't seem to find the Poser cache anywhere on my computer, though.  Ive looked through the Windows folders, users folders, done a search for all 'Poser' files and folders... nothing.
