Somewhat unrelated issue, Mac OSX 10.6 - I notice that having my Runtime on a Network Attached Storage device, as opposed to a local drive will not render anything at all. I don't really care - just move what I need to the main drive before I render.

On another unrelated note, 10.6 is now "future-proof" at the expense of "backwards compatibility", so some "older" apps / legacy code compiled before the release of 10.6 requires Rosetta to be installed in order to work, which is NO LONGER installed by default on 10.6. Not faulting Poser specifically, because I've noticed this with Maya and Mudbox under 10.6.

In defense of the Windows users, in the future, please offer a more precise explanation of your problem in your initial post. Your screen shot of the Activity Monitor (equivalent of the Task Manager for the Windows people) in your original post is not complete and offers no useful information.
