Is this a new feature or a short circuit between the headphones?

Hi. I recently moved to Sonar Pro and have noticed the following issue (if it indeed be an issue). When working in track view, the track I'm focused on deselects after a paste and I need to re-select it before highlighting another section or risk inadvertently selecting all tracks. This is an annoyance when trying to edit a track quickly and did not occur in X3 as far as I remember.
Is this a new feature or simply a setting I'm missing.
 
Thanks, David
