title: CreateObject randomly throws "A system shutdown has already been scheduled" error
body: <p>I googled and SO'd, and nothing.</p>
  
  <p>My job revolves around making my co-workers lives easier.</p>
  
  <p>Currently, they are using very clunky spreadsheets designed 10+ years ago.</p>
  
  <p>In the process of migrating their tools and reports to the local intranet using PHP, i have configured a spreadsheet that downloads that persons permissions based on their Application.Username</p>
  
  <p>Then a little back and forth with the server to generate a session key, and then <em>pop</em> internet explorer opens up with the relevant tool they selected from a dropdown within the workbook - meaning their session and tools are then purely browser based.</p>
  
  <p>All works great, however randomly, sometimes, when the sub to open the internet browser is triggered a very bizarre error message appears :-</p>

  <p>Upon clicking Debug, the following function is shown, and you can see for yourself which line is highlighted in yellow.</p>

  <p>I can confirm i do not have any tasks at all within my taskschedule. When i end this, and run it again, chances are it runs just fine.. it is just <em>sometimes</em> that this error pops up.</p>
  
  <p>Please help! Thank in advance.</p>
