onovercrop

Hello,

I am using one a png image for all my buttons in a panorama, and am cropping parts from it for the buttons and the images for the onover event.

<plugin name="help"
	url="buttons/buttons.png"
	crop="96|0|16|16"
	onovercrop="96|16|16|16" />

The problem is, that when I am holding the left mouse button pressed while being on a button and moving the mouse away from the button it keeps the crop from the onover event and does not go back to the original button image. In my example the button says red (onover colour) instead of going back to black (normal colour).
Is there any workaround for this problem?

Thanks in advance,
Magnus

Thanks a lot for the help again, michel.
Your solution works fine for me, even when using a new picture for ondowncrop it switches back to the original picture when I am releasing the mouse button.

I was hoping to get around using another attribute but as long as it works I am fine with this solution.
