Recent Posts lists recent posts you havent viewed. Since you viewed your own posts when you created them, they won't appear in Recent Items until someone else responds.
That said, I have seen a delay of several minutes between when the modification date/time updates in the lower list and when it reappears in Recent Items due to someone else responding to them.
There's also a bug in forum software such that posts that are several months old will not reappear in Recent Items when someone searches it out and posts a new response in it.
Thanks again Phil. I was just wondering.
I had a problem with file name not showing in the "window" drop down list, just a number (between 1 -10) and a balnk name. Now I cant find the post, or your answer. It happend again & I don't remember how to fix it.
