Same thing happens here occasionally, with Firefox.
It mostly happens on very large pages (my setting is 100 posts per page, what with broadband and all). About 70-80 posts will load, but the last one will be cut off.. I'll see the poster's name and avatar, and the title of their particular post, but no content, and nothing at all below it, just the end of the page.
Only happens once every.. I dunno.. twenty or thirty page loads for me. I've noticed on several occasions that the "cutoff point" will be on one of my own posts, but I don't know if this is a coincidence or not.
