brewgirlca, from your system description, system memory should not be an issue. Have you tried other texture sets (besides Thornes) in the same scene? I'm guessing that there may be a texture path issue rather than a memory issue. As far as purging memory that also should not be an issue, Poser 7 does have a "Reload Textures" selection in the Render drop down menu. This should allow a "texture refresh". I don't have Silvers Tomara or I'd play around a bit. Sorry can't offer more help...
