What I ended up with is a div that covers the map and then I did something like:
var elem = document.getElementById('myDiv');
elem.addEventListener( 'click', stopPropagation, false);
elem.addEventListener( 'mousedown', stopPropagation, false);
elem.addEventListener( 'mousemove', stopPropagation, false);
elem.addEventListener('mouseup', stopPropagation, false);
elem.addEventListener('mouseover', stopPropagation, false);
elem.addEventListener('mouseout', stopPropagation, false);
where stopPropagation is:
function stopPropagation(e) {
if (e && e.stopPropagation) evt.stopPropagation();
else if (window.event) window.event.cancelBubble = true;
}
Then I just hide/show the overlayed div as necessary. Works like a charm.
