Somehow the problem has gone away..  didn't really do anything other than change the ammount of memory allocated to PS.. had it set at 90% and reduced it to 80%.. that seemed to fix it..

I mainly work with RGB's so I dunno if it would have been the same w CYMK's..

anyway, it seems to have sorted itself outbut will try that if it decides to come back :)
