following Microsoft's instructions actually worked

I have a Windows Vista machine with Office 2007 installed. Oddly, in PowerPoint, I can click an email icon and directly email the open file, without having to make it an attachment, but I can not do this in Word or Excel. Or rather, I couldn't. The icon was there but nothing happened when I clicked on it. I, bravely, followed Microsoft's instructions to edit the registry keys. Scary thing to do, but I figured if I was careful, I could revert it back. Plus, I have a complete system backup on DVD. After following the instructions and rebooting, the email icon works in both Word and Excel. Woohoo!
