Okay... 1) Mac or PC? 2) XP or Vista (if PC)? 3) Contact DAZ about it? I ask all of this because, well... They don't even touch common libraries or DLL files (D|S uses Qt for its UI, doesn't use Python, and nobody (that I know of) modifies OpenGL's stuff. The only common points are the Poser files themselves, which are read, not written to by D|S. So, umm, whadda? /P
