Well, you were right (again).
Took the time to implement most of the changes you suggested (The install button is not there yet, but it will be before the end of the week).
So I came back to this post just to say thanks once more and to tell you that it worked, and that it would not have got this far (actually, it would not have got anywhere) whithout your help.
I’ll create a new thread on the ZTools forum and see if I can get a few testers, and will sleep a little, for a change.
Thanks a lot!
