For the last two years I have had no problems emailing photos on Windows 7 Live Mail.  Now, when I click on a photo, then click on "email," then on "Attach," and then on "Send," which has always worked in the past, the system appears to be sending the email, but locks up.  When I look at the details, it shows the process stopped about half way through.  It won't even let me abort sending the email with the attachment.  I have to sign off my computer and re-boot to get out of Live Mail.  Any helpful suggestions?
