I found a little problem with Cross Domain Tracking when target is set to _blank. The link don't open in a new window.
I found a workaround. "_gaq.push" prevent "return false" to act normaly. So i set a timeout to "gaq.push" to force return false to execute immediately.
Here is the code replacement i make in google analytics for wordpress v4.3.5 :
frontend/class-frontend.php Line 367
$trackBit = '_gaq.push([\'_link\', \'' . $matches . '//' . $matches . '\']); return false;"';
$trackBit = 'setTimeout("_gaq.push([\'_link\', \'' . $matches . '//' . $matches . '\'])",100); return false;';
Is there plan to fix these problem ?
