Hi Lawrence,

Hmmm... perhaps I _am_ misunderstanding you. With the current version,
right-clicking on an isophote should result in getting the words "Nebula
Isophote". You might indeed get the wrong object at first, if there
happened to be a star close by; it might take some use of "next"s before
Guide finally puzzled out the right object. But it shouldn't take many
"next"s. I can't think of a way to have nebula isophotes on-screen,
but not be able to right-click on them. (Except by using the older
version. And we've just ruled that one out.)

Anyone else seen nebula isophotes (or, equivalently, Milky Way
isophotes) on which you've not been able to right-click? Any pattern
of a "it happens when I do this" sort?
