The OS interprets "long click" as "right click".

> Now the problem is how to prevent them from showing is a finished project. I didn't see a Preference that would prevent the Halos from showing. And, I don't know if that would be a good idea since one of the things I talk about with students is that they can find out how something is done by opening a halo and then the scripts. Anyway, one problem solved.

Not a good idea along the "authoring is always on" line of thinking ...
