Hi: I am using version 7.0.2.132 which I beleive to be the latest release. I am using open GL (hardware) and I will see what happens if I switch to software. It was suggested that I trash the preferences files but doing so did not resolve the issue. Oddly enough, both P6 and P7 on my G5 work properly and the issue that I am experiencing only exists on my 8 core Intel/Mac with 4gig of ram and an NVidia Quadro FX 4500 for which open GL should be a breeze. All of the drivers are the latest available.
