title: Windows("MyWorkbook").Visible = False unable to edit other files
body: <p>When I use <code>Windows("MyWorkbook").Visible = False</code> then I'm able to open other workbooks but unable to edit or even click on the new worksheet/do any manipulations.</p>
  
  <p>Is there a way to edit or change any data in the opened workbook?</p>
  
  <p>Thank you</p>
  
  <p>This is the program i was speaking in the comments.</p>
  
  <pre><code>Private Sub cmbsendmail_Click()
      Windows("ETY Tracker V1.2.xlsm").Save
      Windows("ETY Tracker V1.2.xlsm").Protect
  
      Call Mail_Every_Worksheet_A1
  
      Range("C10:AH10").ClearContents
      Unload UserForm2 x Unload UserForm1
  
  End Sub
  
  
  Private Sub cmbsendmail_Exit(ByVal Cancel As x MSForms.ReturnBoolean)
      Range("C10:AH10").ClearContents
  
      Windows("ETY Tracker V1.2.xlsm").Save
      Windows("ETY Tracker V1.2.xlsm").Protect
