Vista - mailto link in web page a problem

I have a webpage with a link like:
mailto:someone@xxxxxx

In windows XP clicking this link activates mail client (Outlook in my case),
allowing user to fill in the email and send it. The webpage containing the
mailto link remains displayed in IE7 browser. Fine.

In Vista, clicking this link also activates mail client (Windows Mail).
However, it also loads mailto:someone@xxxxxx into the IE7 browser
address window, then generates message in browser window "Internet Explorer
cannot display the webpage". Of course it shouldn't even be trying to
display a mailto: as a webpage.

Is there a setting somewhere to get rid of this wierd behaviour?

Thanks for help.

Control Panel/Default Programs
click the 'associate a file type or protocol" link, and scroll down to the
protocol setting for mailto. Highlight it, and click the "Change Program"
button.
