Once I send a second email, it remains hung up in the outbox and I can no longer use Windows Live Mail

Original title: Windows Live Mail 2012 Under Windows 7 hang up

WLM was working fine for months. This problem just started. I would appreciate any help in solving it. I have tried repairing the program but didn't help. The following are several sequences of events that help define the problem.

1. Open WLM

2. Send message, it sends OK

3. Close WLM

4. WlMail.exe is still running in task manager

5. Try to open WLM

  A box opens with message:  Sending email using ........   Not Connected

6. End process WlMail.exe

7. Start WLM

8. Send message, it sends OK

9. Send 2nd message, it hangs in Outbox

10. Close WLM

11. Try to open WLM

  A box opens with message:  Sending email using .........  Not Connected

12. End process WlMail.exe

13. Open WLM

14. Close WLM

15. Try to open WLM

  A box opens with message:  Checking for new messages on ......  Not Connected

16. End process WlMail.exe
