Thanks so much for your timely response Peter - I found the
CTA4 manual's location from your reference. It seems, however, that regrettably and ununderstandably since I am still evaluating a free trial version of
CTA4, I am unable to download the
CTA4 manual. It seems a bit counterintuitive doesn't it - being welcome to have a free trial evaluation of
CTA4 but you can't have easy access to the manual! I'm I missing something?
