Auto-close workbook after opening another workbook

[natefarm]

I have a workbook with a userform that closes the workbook when the user closes the form.

Sub Auto_Open()
    Sheets("Background").Select
    MgrForm.Show
    ActiveWorkbook.Close (False)
End Sub

One of the command buttons, when clicked, opens another workbook, feeds some data into it, closes and saves that workbook (I have my reasons), then opens it again, running the auto_open subroutine, which is similar to the above (opening a userform, and then closing the workbook when finished). It is my intention that at that point, the 1st workbook would also close, but it doesn't. Here's the code:

    Workbooks.Open Filename:=Range("DBPath").Value
    Sheets("Prestarter").Select
    ' Copies data to workbook
    ActiveWorkbook.Close SaveChanges:=True
    Workbooks.Open Filename:=Range("DBPath").Value
    ActiveWorkbook.RunAutoMacros xlAutoOpen
   Me.Hide

I put a debug stop on the "ActiveWorkbook.RunAutoMacros xlAutoOpen" line and on the "Me.Hide" line. It stops on the first one, and when I proceed, it opens the 2nd workbook and userform correctly, and closes it when I hit the Close button, but never reaches the Me.Hide debug stop. It just exits from the user form but doesn't close the workbook. Any suggestions on how why it doesn't hit the Me.Hide code?
