I'm also using Hex almost exclusively. 
I must be lucky because I've never really had any problems with it - especially not with the newest version.

Of course I've had it crash - but no more than Poser. I've learned to save often in both proggies ;)

Hex is a lovely program. Very easy to model in. And the models behave well in Poser ^_^

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
  Using Poser since 2002. Currently at Version 11.1 - Win 10.
