I have Poser 4 w/pro Pack(version says 4.2 Curious Labs)<< Is it 4.2.1.179 or just 4.2? If it's not the first set of numbers (you can find out by starting poser, going into "help" on the toolbar and checking "About Poser") then you might want to download and install the Poser 4.03 and the Pro Pack SR3 from Curious Labs. I don't know if that will fix your problem, but it might - stranger things have happened. :) Just so you know, Poser can act really weird sometimes. ;) Kate
