How can I delete the entire content of a 'sent items' folder in Windows Live Mail in one go when, having right clicked, I am not offered the means to do so?

Copied from microsoft web site.

To delete all: Highlight one and Ctrl + A will highlight them all. - Delete.

To delete a section: Highlight the first one you want to delete. Scroll down to the last one and click on it while holding the Shift key down. - Delete.

let me know if that works or not for my records....
