I have been having a few problems with this too. The plugin seems to have stopped automatically adding the rel=”lightbox code to images. If I look at one of my posts from a week ago and view source, I see that it is there and the images load in a lightbox. But one I did recently does not have the rel=”lightbox in the source code when I view it and it does not load images in a lightbox. It appears that for me the autolightboxing no longer works.
The only thing I changed was the Media settings and made the medium images max 600 px wide as that is how wide the blog is.

Any ideas?
