I note that if the last linked Runtime when I closed P7 is my 22+ gig  P5 Runtime, Poser takes longer to load the next launch than if it last closed linked to my smaller (10 gig) P7 Runtime. 

I also recall the tip about closing Poser with just a one-item Runtime linked and Poser is supposed to open up lightning fast, but I don't know because I never tried that.
