I have a circuit in my house with a funny characteristic, and I'd like
to track it down. In that circuit, I measure a slight voltage
difference between power and neutral at a light fixture when the switch
to that fixture is off. Yet, my meter shows no continuity when I try to
measure resistance. Other circuits do not show any voltage when they
are switched off.

I assume this means that the neutral on the peculiar circuit is not at
a common ground with the 'real' ground. It does not strike me as
inherently dangerous, yet it seems like I might as well sort out the
problem. Anybody seen this and have a recommendation on
troubleshooting?

It is probably nothing to worry about. If you are using a digital meter it
is most like picking up some induced voltage from other conductors near it
or the switch could be leaking a very small ammount. How many volts are you
calling 'slight' ?
