When pre-hovering while zoom loading and using mouseTriggerEvent: 'click'. In Firefox, you would have to click twice. Not a show-stopper, but worth fixing.
When using gallery mode, after clicking a gallery image, the zoom window could be made to pop up when the zoom image hadn't finished, thus displaying an empty zoom window.
When using variable magnification and depending on the aspect ratio of the lens, the lens could be made larger than the small image (i.e. zoom image getting too small).
