Rotated slide image is cut off

[MobileMaggie]

When elongated slides (from the Miniature expeditions) are rotated to turn the labels right-side-up, not only does the image window not rotate with the image, but dragging the image across to one side completely is not possible - resulting in a cut off view.

For example, the below image is dragged as far right as possible, but is not legible.
