Bicycle Mechanics - rear der tension pulley noise?

My girlfriend's rear der makes a constant clicking noise. It sounds like the chain is rubbing the inner plate of the cage at the tension pulley. Took it to LBS and they said the chain is fairly new, right size, the pulley bearings feel good, the pulleys are not worn and nothing is bent. Yet it clicks as every link goes by the cage. Any ideas? It's a 8 cog 105 (I think)

You sure it's clicking the cage and not the cassette cogs? If the latter, then a simple adjustment of the barrel hut on the RD should do the trick.

I was just looking at a junker bike I picked up for $15 a little while to check some other things (it IS a FH:)).
Anyway, cranking the pedals gave a very similar sound to what you describe. The bike has been sitting a few? years and the chain is stiff enough that it doesn't QUITE flex enough. Almost, but no cigar. You can see the pulley slightly "twitter" with the sound.
Does your chain have some "gooey" lube or something on it that prevents it from EASILY flexing?
