Enable Scrollbars in Secure Viewer?

We have an HMI (IWS v8.0) for a large vacuum process control project; the HMI project runs on a system using a fairly large 16:9 aspect ratio monitor.

I've successfully configured the system and webserver to allow connection via either Web or Secure Viewer Thin Clients. For a number of reasons, the Secure Viewer is a better solution for my group.

I've noticed that while the Secure Viewer window can be resized, it never has scroll bars, and this can lead to problems viewing or accessing indicators and controls in the edges of the screen, even when maximized.

Is there anyway to enable scroll bars in the Viewer, or to make it scale its contents to fill the window?
