This is a two part question:

1) Is there some way to keep the custom 404 error article from showing up in the "Top 5 Popular Articles" list? Right now, after just playing a little bit, the 404 error article has already climbed up to the most popular article on the site. I don't want this to be seen in the popular article list.

2) In looking at the 404 logs, I noticed that the most popular URL causing 404 errors is "administrator/separator". Does anybody know what this is or why it is showing up as a generator of a 404 error? I've noticed that these 404 errors are being generated just while moving between tabs in the JoomSEF control panel.

Thanks for the help!

PS: I'm using 4.0.6
