HTML5 resizing / VOX files

The flash based XOT will resize content when the window resizes. So if your LO opens at 800 X 600 and the user selects to open the full window, the content images and text all seems to resize in relation to the window. This isn't happening in the HTML5 version. In HTML5 the images and text sit in the upper left corner at the same size they were, which pretty well disables opening the window full size. Is there any way to make the HTML5 version size proportionally?

Thanks
