Thanks Jim - I'm renewing an older interface that used a scripted solution
along the lines you suggest - but they always look unprofessional. It seems
to me that we have all the terms needed in the langauge to create an
interface that allows the user to select objects in the same way as the Rev
GUI does - so I'm trying to see how far it is possible to push that.

What I really don't get about the example I post is what the difference is
between the status of the selected group - in one case you click on an
object within the group and yu can move the group around - in the other you
trigger a different behaviour - what is the difference in both case the
group is selected and the pointer tol is selected - don't seem to be able to
focus on the group....
