The patrol link for patrolling new pages is usually at the bottom right corner of pages. In monobook skin there is a css rule for this:

div.patrollink {
	clear: both;
}

This is missing in the vector skin (and maybe other skins). On pages with floating elements like images or infoboxes this sometimes places the patrol link higher up on the page.
