title: SSMS not responding without any error message
body: <p>SSMS was working great until last night, and now it is not responding.  In windows task manager it shows it is running, but when I click on it, it is not responding.</p>
  
  <p>I have many unsaved SQL Query windows, and I don't want to lose them.</p>
  
  <p>I tried using <code>ALT + M</code> and see if activity monitor is open and I also tried suggestions from <a href="https://sqlblog.org/2009/06/25/what-to-do-when-management-studio-hangs" rel="nofollow noreferrer">https://sqlblog.org/2009/06/25/what-to-do-when-management-studio-hangs</a>.</p>
  
  <p>Any response is highly appreciated. I am using <code>SQL server 2008 R2</code></p>
