Office Picture Manager e-mail option greyed out

[Molasses]

Hello,

Using the Office Picture Manager, I select a picture, then select e-mail
pictures.
Within this pop up on the right hand side, i am supposed to be able to
Attach, Display as previewed, and then create message.
Only thing is all of the selections are grayed out and nothing can be
selected.

Questions are,
Is Picture Manager hard coded to use Outlook or Outlook Express only?
Are there any registry settings which might be massaged to point to another
e-mail program?

Thanks
