Thanks both.
foc, it was the first of those links of yours that got me thinking i.e. the Roger Hicks article in Shutterbug mentions ways of using FX 50 that Paterson in its instructions for using may or may not mention. So I wondered if Roger Hicks was simply repeating what Paterson had said or not, hence my interest in getting hold of the actual Paterson instructions
There was a much earlier thread here on APUG when FX50 was launched but there were only a few participants and of those all who might have obtained the developer and the instructions have long since gone
