I noticed this on my site and went to the Dolphin demo site to see if it was occurring there as well and it is. When you go to photos home page, the ajax loading for the pagination is working. However, it is not working on other parts of the photo section. For example, click on the recent section and then click on the pagination links, say 2 or 3; the whole page will reload instead of just the photo thumbnail section. This holds true for Top, Popular, and so forth.
