Loading execute-pings.php automatically ‘cancelled’

Is there anybody out there?

In the footer of the admin pages, there’s a hidden iframe which is loading the execute-pings.php file. This handles pingbacks and trackbacks that are queued and waiting for processing. These generally take a while to run, so if you have a lot of them queued up, they won’t finish running before you go to the next page on the admin screen. You’ll see the cancelled thing, but that’s perfectly normal, as you’ve changed pages. Eventually, it’ll run through all of those that are queued and it’ll stop doing it.
