title: Powershell ISE run strangely
body: <p>I'm new on Powershell scripting and i've one issue.
  When i start scripting, my stuff runs well but since yesterday, the script execution runs differently than before.</p>
  
  <p>Now :</p>
  
  <ul>
  <li>The console print all the variables values when not ask</li>
  <li>Open pop-up for read-host command (this is a console application)</li>
  <li>The securestring isn't decrypt by the application anymore</li>
  <li>"Enter" key must be pressed 2 times to enter values when the script
  runs</li>
  <li>Some commands are not found</li>
  </ul>
  
  <p>Any ideas guys?
  Thank you (and excuse my poor english ^^)</p>
