title: Why does 'msg * alarm' disappear after a while?
body: <p>I have a small powershell script which allows me to quickly set an alarm for myself. It basically just waits a specified number of minutes and then calls </p>
  
  <blockquote>
    <p>msg * alarm!</p>
  </blockquote>
  
  <p>This works well - a message box pops up. The only problem is it disappears after a while - so if I'm not at my desk, I'll miss the message box.</p>
  
  <p>According to the documentation, <a href="https://technet.microsoft.com/en-us/library/bb490796.aspx" rel="nofollow noreferrer">found here</a>, this is the behaviour when I don't specify a time value.</p>
  
  <blockquote>
    <p>/time: seconds   : Specifies the amount of time the message you sent is displayed on the user's screen. Once the time limit is reached, the message disappears. If no time limit is set, the message remains on the user's screen until the user sees the message and clicks OK.</p>
  </blockquote>
  
  <p>However this isn't the case and it does disappear. Right now, I have to specify an arbitarily high number for it to stay.</p>
  
  <pre><code>    msg * /time:999999 alarm!
  </code></pre>
