Mouse Listeners

Hello there. It is possible to have 2 mouse Listeners on the stage? one to be activated if the mouse is on the last 50 pixels of the stage, and the other one to be on the last remaining part of the stage. It is like I have a large image that is bigger then the stage and then I have to drag her to see it all and if the mouse is on my 50 pixels I can not be allowed to drag it. And on the bar I have buttons that I have to make them click.
How can I do that?
Thank you.
