Chrome, latest version. (on winxp, but the same is happening with ubuntu)

I just tested it here,
 * 1) typed "search" in the search box on this page
 * 2) held "ctrl"
 * 3) clicked on the first result
 * 4) released "ctrl"
 * 5) search page was replaced by first search result, instead of opening in a new tab.
