Problem with cropper ui 1.2...

When i click on page outside of 'EditImage' the crop is updated to a box with the dimensions of ratioDim:, What might I be doing wrong? here is my initialization.

function InitCrop()
	{
		new Cropper.Img(
			'EditImage',
			{
				ratioDim: {
					x: <?php echo $PosWidth; ?>,
					y: <?php echo $PosHeight; ?>
				},
				displayOnInit: false,
				onEndCrop: onEndCrop
			}
		);
	}
