All of the links in the sidebar on the right side of the site on any page under the subdomain forum.piwik.org have a bug when trying to open them in a new browser tab.

When you ctrl-click or command-click any of the sidebar links to open them in a new tab, they will open in both the current page and the new tab. Of course, they should only open in the new tab and leave the current tab on the current page. This bug is not present on the piwik.org home page or any pages without the forum.piwik.org subdomain.

I tested this with Firefox 10.1 and Chrome 17 on Mac OS X
