Agreed, the stability should be improved (although the Mac isn't as much a single target as it used to be) - and as for Poser 5... what it can't do is, by now, legendary... what it can do I doubt we've even envisaged yet. Some of the improvements over Poser 4 belie the "Poser" name IMHO... and some of it is comparatively easy to do too (I was quite proud of this image I produced last night, yet it was so easy to do!)
