Goodness thank you both ! Firstly to bring you up to date I've also been on a Daz forum in the last day or two which I think is self-explanatory trying to understand it all as well, to the extent that they've now created a new thread about it as they can't understand what's happening either ! Had to cancel trip today due to bad weather....

Meantime I'm ok with all the library stuff in principle thanks though still having to refer to the manual all the time but this is routine stuff and just the learning side. But as you'll see from the Daz thread the basic problem currently seems to be that there's no Save option only Run which made me wonder if Debut is incompatible with something, and why I decided to re-install it again this morning. Problem was  the same thing kept happening only this time it crashed whilst loading all the library elements. Incidentally I created the temporary file labelled Pos as I gave up looking for the original Poser library, even though they were listed on the right hand side of the workscreen.

So fortunately not having paid for anything and as it's all getting a frustrating muddle this end, I really want to get on and not waste any more time with Debut. So I've uninstalled them both and now want to trial/ buy (?) whatever Poser version that suits permanently, so whatever you recommend at the cheapest price will be great thanks. It'll be more learning but as I've finished Chapter 7 it makes a whole lot more sense to go down this long term and practical route rather than fiddling around any more with Debut I think...
