Sorry Jim, really not observer error, but there does seem to be consequesnces and it may be pure chance that it worked for me in certain circumstances, see the latest on the other thread:

Also look at post 19 on that thread and see if that helps.
That's the only 2 explanations I can think of as to why it's working on my iMac, someone please try it - I've got a working system and I don't want to mess that up just yet, but I don't know how stable it's going to be.
My only real issue now is that I can't get my MBP to do the same thing as my iMac (on lots of CC stuff, not just En).
