How do I add different email clients to the Email tab in My Documents

New here folks - hope someone can help with this?

When in the my document folder - there is an option to highlight a file and click the "Email" link which is present on the light blue bar at the top of the screen.

On another Windows 7 machine I have seen - a dialogue box pops up when you click this link and you can choose which email client to send this the file to.

Does anybody know how I can make this happen - and get such a dialogue box to show options for AOL 9.6 software and or Outlook 2007 / Windows Mail. I have all 3 running on my system and different email accounts setup in all (happy to leave it that way).

It would be good to have the option to send an attachment to any of the 3 programmes.

Thanks in advance

I wonder if the button works for you at all, like to use one of the email programs (the one designated as default).
