I just tried it. I switched to Orange Sky and tried About, Archive, Links, etc. and all was well within Orange Sky.
Then I tried Stanch and went to the About page but it popped me right back into the Falling Dreams theme. I tried Orange Sky again, hit the About page and I got popped into the Kubrick theme. I tried it again and it worked the way it should: all Orange Sky.
Stanch seems to have the least staying power of the three themes. Hitting all the pages always takes me to Falling Dreams. I also got Kubrick several times.
Something is definitely amiss but I don't know enough to tell you why it's happening, just confirm that it is. Sorry!
Edited to add:
Oh, wait... your photo gallery is supposed to be in Kubrick, right? It's not a page, but another site altogether. So forget the Kubrick comments!
Heh! I should stay out of this trouble-shooting stuff!
