Thanks for the reply, but all that did was change the star display so
that they became strangely fuzzy, but still no isotopes.

One thing I have noticed (and which I mention in case it aids diagnosis)
is that the isotopes toggle does do something: If I go to (for example)
M42 at level 6, it toggles a few nebulae (yellow squares) on and off --
their labels stay there and the squares toggle off as isophotes toggle
on, and vice versa. (e.g. LBN 956; S 278).

Anyone else have any bright ideas?
