And what email software are you using?
Normally, clicking on an email link in a web page should open the 'Default' email software to send the email. Check that you have set your default email software correctly either by;
1] In Internet Explorer goto Tools > Internet Options, or
2] Goto Start > Control Panel > Network and Internet Connections > Internet Options
Then in Internet options click the Programs tab, and make sure your email software is selected in the section for Email.
This assumes you are using Windows XP or lower. You didn't say.
