Hi Lawrence,

To find an object in a user-added dataset, you'd need to use
Go To... Go To .TDF Object (last item in the menu). _Then_ you
can select the LEDA Million Galaxy catalogue.

But the comments I made in my post were just about turning the
data on. Does _that_ work? Are you seeing galaxies on the screen,
and are you able to right-click on them and get data about them?
