need advice on how to switch back on the hair colour for poser strand based hair.  normally when i colour the poser 6 hair colour black and other colours.     when i begin to adjust the hair length. the hair turns instant blonde.  that's normal. no problem.               but, today.  the hair even the pre done poser6 hair in the hair cateogy no longer changes to any colour.     it just stays black.      i've tried to  adjust the hair colour nodes in the poser 6 material room.                but, nothing happens  i suspect something is very wrong with the colouring of the poser 6 strand hair.            i suspect an bug in the poser 6 system.   i know how to change the colouring on all of the hair colour nodes in the material room.  but, no change on the colour so far.            the hair will not colour as it should do.  i've done it before.  changing the colour of the hair to red or blonde or black or whatever.  so i can't understand to why it's non functional.  please can u help.  it's driving me crazy.    is there something i should be switching on in order to restore the hair colouring node system?            have i accidentally switched something off?             this shouldn't be happening at all.  also...  are there any such poser 6 strand based ready made hair morphs for use in the poser 6 hair room.          i desperately need an swept back hair and hair fringe for my poser 6 jessi.         still need to be able to change hair colouring.   

if anyone can help with these issues i will be very grateful indeed.  awaiting reply jason
