Exit button not working in Captivate 7 published output

Hi. I am using Capivate v7 and am experiecing this problem with published output:

I am using an Exit button that runs the standard javascript code

     javascript:window.close()

so that the user can exit the presentation. The button works fine when I test out the presentation using Internet Explorer 8, but when I generate an output and try running the .swf file, the button does not work.

How do I get an Exit button to work for the .swf output?

Thanks,
