Yes, the problem we traditionally refer to as crosstalk is taken care of in Poser 5 (although in a way that introduces side-effects, e.g. no crosstalk from a charcter to an item of clothing that requires crosstalk). The newer manifestation of crosstalk symtoms in injected figures using readscript is not addressed in Poser 5 however (wasn't known about at the time of Poser 5 release), and the fix I referenced above is still required in Poser 5 if you want to inject more than 1 character in the same scene. (Note that in Poser 5 you do not need the intervening Mill Nulls to protect against later "traditional" crosstalk after the multi-inj-figure scene is saved and re-opened. This provides a workaround if you do save a scene with multiple injected figures in Poser 4 and forget the Nulls.)
