I am having a problem with onLoad event of an iframe on Google Chrome. I created an iframe and set value for its src attribute to get a file from server. While server is processing, a waiting box is displayed until client gets the returned file. I tried to use the onLoad event of iframe to detect when client get the file to turn off that waiting box, but on Google Chrome that event handler does not work.

With Firefox, when client gets a file, a Save to popup will be displayed automatically and event load will be fired, but this is not happen on Chrome.

Could you please tell me how to handle this issue? Thank you so much!
