Tablet Orientation Change logging out user

Hi,

We have a tablet that we are wanting to use for our MES application on the Shop floor. It will run the perspective application on a web browser. The application is running well. One issue we are facing is, when the orientation of the tablet is changed, its logging out and loading the login screen. Now to manage we have the orientation locked, but we need both views as some things are better viewed in a horizontal orientation as the tablet.
