Time to "show us the code", I think.  You're over-riding the Unload to 
minimize to the tray.  How?

I just put this code in a form that lacked min/max buttons:

   Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As 
Integer)
      Open "C:\QueryUnload.txt" For Append As #1
      Print #1, Now, UnloadMode; " - ";
      Select Case UnloadMode
         Case vbFormControlMenu
            Print #1, "vbFormControlMenu"
         Case vbFormCode
            Print #1, "vbFormCode"
         Case vbAppWindows
            Print #1, "vbAppWindows"
         Case vbFormOwner
            Print #1, "vbFormOwner"
      End Select
      Close #1
   End Sub

Compiled it, copied it to an XP VM, and ran it twice.  First time, I 
closed the form with the [x] button.  Second time, I logged off the VM. 
 Here's the output file:

   4/30/2012 11:56:03 AM        0  - vbFormControlMenu
   4/30/2012 11:56:18 AM        2  - vbAppWindows

Clearly, Windows is sending the shutdown message.
