Yup.
See other message to Clive.
I have seen this magenta/purple report before on 9.5" aerial 
IR....but I wasn't sure this applied to both HIE/Aerographic and 
EIR/Aerochrome. 
Thought I had saved that message, it was even before this list 
existed, from the PhotoForum list, involving someone in Australia, 
who later also joined this list (not sure he is still present).
Can't recall a cure for sure though....
