I just noticed an odd behavior with lightbox. In configuration->images, I changed "IH large image maximum width" from 600 to 640. Now, when I click on an image that's larger than 600, lightbox either either displays the image at 600 pixels wide, or just hangs without displaying the image at all.

I've cleared both the cache in IH2 and in my browser, and repeated this test.

Is it possible that during installation, lightbox examines the maximum image width setting, and stores it, instead of re-reading it whenever it needs to? Any other ideas what might be going on here?

Thanks.
