Null prompt in Dashboard swf

Hi,

  I'm using Dashboard 4.1 SP 2 with EPM10 SP 16.

  After creating a simple dashboard with a "Connection Refresh Button", i ran it in "Preview" mode. After clicking the "Connection Refresh Button", there's a prompt asking for userid and pwd. After entering the userid and pwd, the dashboard refreshes.

  I exported the above into a swf. I tried opening it in IE. After clicking the "Connection Refresh Button", i get a prompt with Null and 2 blank buttons as shown in the attached.

  Any ideas how i can fix the above, so that i can get a valid prompt?

Thanks,
