I have an account on Hotmail (well now Outlook.com) and when I go to "Insert" - File as Attachments, and select it from Windows Explorer, immediately Internet Explorer crashes and restarts to a "new" message in Outlook.com.  This ONLY happens in Internet Explorer version 10.0.9 on Windows 7 Home Premium Service Pack 1.

I can attach using Google's Chrome or Mozilla's FireFox browser.
