Quote - One thing I noticed is in the process manager, winxp64 still shows poserpro with the *32 extension on it. So does xp64 think poser pro is a 64 bit app?

PoserPro is a 32bit app but it has two Firefly render engines: one 32bit and one 64 bit. If you want to use the 64bit Firefly renderer you need to Render to background. You can access this in the Render settings dialog window under send Render to or in the little drop down menue on the document window Render to background.
