Topic: back button with left aligned images

I have finally decided to upgrade to 1.4 and it is marvelous Felix. The one thing I am trying to accomplish however is to have the back button active on the current image. I have images left justified and I would like the users to be able to go back without having to click the actual arrow, just like the images on the right. For clarity, when the images are left justified the only way to go back is to actually click the back button itself and not the image.

Is the button area controlled with the mClip_mc in the stage manager? I don't see an instance which would dictate the clicking area in the Am I missing something? Any of you found a solution?
