A couple of Norton Internet Security questions

[offTopic]

I've got a couple of questions concerning content either linked from 2p2 or actual threads on the forums.

i) Some pages containing pictures (not those kinds of pictures) that were linked in LOL don't display the pictures when the page opens.

ii) When threads get very long, there is no content displayed - there's just the 2+2 Forums header.

In both of these cases, when I turn NIS off, either the page with pictures displays, or all of the posts display. Does anyone know what the specific configuration issue is here? Any help (aside from, "don't buy NIS") is appreciated!
