Firstly, when posting to the Forum please state what version of Poser we are dealing with here. If we are talking about Poser 5 then these memory issues are curable by installing Service Release 3 from the Curiouslabs website. As for allocating memory to an application... in Windows, no chance. You can assign a higher processor priority in Windows XP and 2000 but I'm afraid Windows handles how much memory each program receives. I do beleive this is possible if your using a Mac. Hope this helps. NeilP
