It's the little things... v. 3(?).

Should you wish you take advantage of the integration between Microsoft Office products and select "Send to: Email as attachment" from within Word, Outlook will obediently pop up a little window for you to enter the relevant address details and content etc. It doesn't automatically use your signauture, but that's a minor nuisance.

However.

That message will take all focus for Outlook, and refuse to move until it is closed (which usually means sent). Which means that if you're trying to compose something and you want to check a detail in your calendar, or another email, bad luck, pal, you can't.

Bad implementation.
