Problem with hotspot and crop function !

Hi,

It seems possible to set a crop onvercrop ondowncrop function on a hotspot (documentation). But it doesn't work with me. The same code is working as a plugin !?
Any suggestion would be pleased.

<hotspot name="Infos"
			 url="plugins/infos_BB.png"
			 keep="true"
			 visible="true"
			 alpha="0.9"
			 effect="dropshadow(2,0x000000,4,0.8);"
			 distorted="true"
			 ath="66"
			 atv="-1.8"
			 crop="0|0|90|80"			
	         onovercrop="0|80|90|85"
	         ondowncrop="0|170|90|80"
			 devices="all"
			 onclick="showinfos();"
			 />

Hi VN2011,

Thanks for your guess.
It's working but it's not really esthetique this way.
No way to get the hotspot "sticked" into the pano ?

Thanks.
