plaxo toolbar for outlook / implementation

Hello,

I'm a new user of the Plaxo Toolbar for Outlook. During the installation process on my computer, it was not necessary to install a .Net Framework.

I'm curious and I just would like to know how is it possible ? How the toolbar is implemented ? [img]/images/graemlins/confused.gif[/img]
