title: Why is Excel / Word 2013 starting invisible?
body: <p>Our Company recently upgraded to Office 2013 since we want to use SharePoint 2013.</p>
  
  <p>We had several issues with the new Office Version but Microsoft has already solved some of them.</p>
  
  <p>Anyways, one thing sitll grinds my gears: 
  Excel or Word <strong>sometimes</strong> starts invisible. It is visible in the Taskbar but the window doesnt pop up. I can click on the Icon in the taskbar but it doesn't change anything. The only way i figured out to show the window, is to use <kbd><strong>[Windows]</kbd> + <kbd>[Arrow Keys]</strong></kbd>.</p>
  
  <p>I can't tell the constellation why this is happening but most of the time it is if there isn't already another instance of the program running.</p>
  
  <p>I don't have Office 2013 at home to reconstruct this but I have seen this on different Computers at our Office.</p>
  
  <ul>
  <li><p>Now does anybody know about this issue?</p></li>
  <li><p>What can I do about it?</p></li>
  <li><p>Is it known to Microsoft?</p></li>
  </ul>
  
  <p>Any help is appreciated.</p>
