Thank you Michael,

I had forgotten that Apple hides the User Library files by default
(tip for Mac users: Cmd Shift . [period] will unhide hidden system files)
So all good now.

While I've got you: there is a bug with interacting with NE interface via MacBook trackpad,
which Max is unable to reproduce because he doesn't have access to these devices (macbook or mac trackpad).

I've not experience any similar issue with Moi v4 interfacing, so it is likely to be specific to Max's
code, but is there something within the rewriting of v4 that has altered the handling of trackpad events
that may have follow on effects? I understand that NE operation is outside your principle concern, but if
there is something obvious to you that may cause this issue, perhaps you could steer Max right.

Either way, thanks again for your help

James
