I have problem with dragover and iframes. In FF everything is OK, but Chrome and IE want not initiate events over iframe.

Please take a look at sample:  http://msdrop.com/msdrop-jquery-test-iframe-frameset.htm

Try drag over and drop sample HTML elements on iframe A and iframe B.

IFRAME A (the same domain) - when you drag any HTML element from parent page over  msDrop.com system in iframe, everything is OK, you can drag over, leave, or drop .

IFRAME B (other domain) - dragover not working from parent page.

How to set  jQuery dragover works  cross-domain and cross-browsers?

Thanks for help
