var e=LL.getEvent();

var it=e.getItem();

//get default icon

var img=it.getCustomIcon();

it.setCustomIcon(img);

var img2=it.getCustomIcon();

alert(img+”\n”+img2);

If I run it on a new shortcut, it writes null null

If I set a custom icon to that shortcut and run the script again, the launcher becomes unresponsive
