Colorcurvature .. Could you try using the Soften Tool or Displacement Brush under the UV & Paint tab.  That is where Hexagon locks up and crashes when I try to use them.  Importing the mesh and doing general face/edge/poly tranlations etc. seem to be ok, just when using the mentioned tools.. CRASH. :D   Also using the 2.5.1.79.

Not that this is a real problem for me, as I also use blender.  But may be for others.

 

Edit : .. I suppose I should also add that this occurs using PoseMorphExporter 2012.1.34 (Which is the latest version I posess)

Consider me insane if you wish, but is your reality any better?
