getURL from HTML email (FLASH)

I have this simple email… an HTML file which contains a Flash .swf movie that contains a button in the last frame that has a getURL command… I send the email, I receive the email, I click the button, the email / .swf never gets the URL and does not open a _blank window.

Any clue? Any idea? Any great solution.

The file works fine from a browser window: http://www.kayeung.com/new_crack2.html
