Cool, thanks Michael, I spoke to my friend who is letting me use Ida under his licence.( He writes and sells software for CNC machining, very smart man)
He said he is happy with the 6.1 version and to buy my own if I want the later version....
Oh well I am saving for a couple of other things so it goes on the list, will persist with 6.1 for now, almost $1200AU to buy 6.4....
