In Google Chrome (dunno what version 'cause it's waiting to update): Link #1 went to http://dw-news.dreamwidth.org/9628.html?thread=1154460#ljcmt1154460 the first time, and http://dw-news.dreamwidth.org/9628.html?thread=1153692#ljcmt1153692 the second time (second being comment above the first), and second link worked in exactly the same way.

I'm wondering if this is to do with the user pic's opening as the page is loading, and so 'bumping' to different levels dependant upon the pic's already saved in the cache?
