Quote - I still get the pinwheel or death (mac) when I try to change anything on the hair prop in shader room - even the tip color, it just starts spinnin'. I might be out of juice - eMac 1 gig ram 1.25ghz.

This is a known bug that any rigged model will crash the shader room preview -- hopefully to be fixed with the 1st service release.... The work-around is to turn off AUTOUPDATE on the preview window before you load any rigged figures.
