I am trying to send word documents directly as attachments from Word 2007 on
my Windows 7 laptop, but no matter what I do I always seem to hang the
programme. I have thunderbird set as my default email client, and no email
accounts on Outlook.

When I did have an email account on Outlook, it tried to send my document
using Outlook.

I can send Excel documents directly using the same feature in Excel.

I have heard that on Vista and Win7 that Outlook is the only email client
permitted for Word 2007.

Anyone have any suggestions?
