I Created cutomized mozilla plug-in for my testing purpose.

in the plugin i am using window.showModalDialog() to open a ".xul" file, and on opening i am using onload event, which calls javascript function to populate some of the value for the ".xul" file. it was working fine before. but recently it is throwing javascript error "NS_ERROR_NOT_AVAILABLE: Cannot call openModalWindow on a hidden window nsPrompter.js:382" and opens the popup window without triggering onload event.
