And I quote directly from the Poser 5 shrinkwrap: "Opening this CD package indicates your full acceptance of the Poser 5 End User License Agreement (EULA) on page 11 of the Reference Manual. You cannot return this product after opening this CD package." From page 11 of the Reference Manual: WARNING CURIOUS LABS IS UNABLE TO ACCEPT RETURNS ON PRODUCTS WITH OPEN CD HOLDERS They restate that two more times on the same page. I see nothing in the manual or EULA about any trial period. And if ain't in the EULA, it ain't there. Period. Oh, and my vote goes to "Slug" as the new name for the new P5 renderer. casamerica
