Thanks for the reply Pete, apologies for the dumb questions, while FSUIPC does lots for me, I haven't done much with it myself.
Yes of course the macro file 737PMDG items from the macro file were in there as soon as I tried to assign buttons.
Don't know what happened with my text copy, I'd just smeared (selected) the text, copied with a Ctrl+C , opened a new .txt file on my desktop, yes notepad, and pasted the text in, and was also surprised to see it as a block of text, no carriage returns. Maybe (????) it had been created with line feeds, no carriage returns ??? No matter, I managed. ( Is Win7 64 Notepad any different to previous Notepads ?)
Thanks again that should be enough info to be dangerous :)
