[OpenLayers-Users] Create Hole in a Polygon

[francescoboccacci at libero.it]

Hi all,
i tried to test the following example:

http://dev.openlayers.org/releases/OpenLayers-2.11/examples/donut.html

but it seems that i can create hole only on IE. Firerfox and Chrome it seems 
that doesn't work. Do you have any suggestion?

Maybe i have to modify this option:

{handlerOptions: {holeModifier: "altKey"}} 

Thanks
