New post indicators disappearing too quickly

Is there any way to keep the new post indicators until I have actually read the post? If I'm moving through the posts slowly the little yellow icons disappear before I even get to them.

I'm not sure if that makes sense. But, I guess, the cookies are timing out too quickly for me. I've looked at the forum settings, but I can't find a way to extend how long before the cookies time out.

Try hitting your browser's "Reload"/"Refresh" button about every half hour. Should reset the cookie.
