title: exec a xlam everytime I open an excel file
body: <p>I have the following peace of code to exec a xlam file when I open the excel file:</p>
  
  <pre><code>   Sub Auto_Open()
        Application.OnTime Now + TimeValue("00:00:05"), "readCsv"
     End Sub
  
     Sub readCsv()
        ....
     End Sub
  </code></pre>
  
  <p>I add it as Add-ins so every file I open has the xlam file on it. If there is no other excel file opened, it works perfectly but after that without closing the excel file I open a second one it does nothing. I need to exec the code even if there is another excel file opened. Is that possible?</p>
  
  <p>I also try to do it writing the code in ThisWorkbook but the result is the same, If there is another excel file opened it does nothing. </p>
