Sorry to skew this thread a bit, but... Katherine, There's a new post (poser g5 optimized by Ede) that seems to indicate what I'd suspected for some time, which is that the Mac version of Poser 5 is not plagued with anywhere near as many problems as the Windows version. The source of course being the Mac to Windows conversion code that was written so very, very long ago. Any chance that THIS could be rewritten before anything else, so we can get responsiveness, speed, and many memory leaks, "file locks" under XP etc., fixed? All these new redesigns for the upper 2 stories of the Poser House are great of course, but if the foundation is crumbling because it's not to current (Windows) spec., then the result remains all too predictable.
