Odd outlined box appearing upon hover and click over images

If you scroll down below the first images (the Portfolio section) you will see a group of design gallery links. When I am hovering and clicking on them I am now seeing a thin outlined box over the image.
This is new and possibly happening since the last update.
Is there a way to fix it so that the box does not appear when clicked on? \
This also happens on the interior design gallery pages when you click on the thumbnail for a larger view.
Any tips to fix this would be greatly appreciated.
