I've noticed a bug on these forums, though I'm not sure if you have an ability to control it.
When I go into a board (such as Studying for the LSAT) and click on one of the topics with the blue "new" graphic next to it, it clears not only the "new" on that topic, but also on the topic immediately below it. All the other topics remain the same.
For example, when I opened this board, "replies timing out" and "suggestion
" both had a "new" graphic. I clicked on "replies timing out"; when I backed out, neither "replies timing out" nor "suggestions
" had the "new" marker.
I'm not sure if everyone is experiencing this or just me. BTW, I use Mozilla rather than IE, if it makes a difference.
