Combo Box text disappears!

I have a combo box that's supposed to show all values in a given database. The procedure works fine until it gets to the end, then for some reason the combo box loses its text. The list items are there, it just no longer shows the item I selected. I ran a quick debug, and it happens right on the first Exit Sub (the one before the error handler.)

Code:

---

Private Sub MasterControl_Click()
    Set fso = New FileSystemObject
    On Error GoTo ErrorHandler
    MasterControl.Text = Replace(MasterControl.Text, " ", "")
    If fso.FileExists(App.Path & "\Databases\" & MasterControl.Text & ".mdb") = False Then
        For i = 0 To MasterControl.ListCount
            If MasterControl.Text = MasterControl.List(i) Then
                MasterControl.RemoveItem i
            End If
        Next i
        Set rs = New ADODB.Recordset
        RecordSource = "SELECT * FROM Headers ORDER BY Name"
        ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & App.Path & "\Databases\Headers.mdb"
        rs.Open RecordSource, ConnectionString, adOpenKeyset, adLockOptimistic
        If Not rs.BOF Then
            rs.MoveFirst
        End If
        For i = 1 To rs.RecordCount
            If rs!Name = MasterControl.Text Then
                rs.Delete adAffectCurrent
            Else
                rs.MoveNext
            End If
            If rs.EOF = True Then Exit For
        Next i
    End If
    OrganizerDatabase.ListItems.Clear
    Set rs = New Recordset
    Set Win32Script = CreateObject("WScript.Shell")
    For i = 0 To Data.Count - 1
        Data(i).Locked = False
        Data(i).BackColor = vbWhite
    Next i
    RecordSource = "SELECT * FROM " & MasterControl.Text & " ORDER BY SiteName"
    ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & App.Path & "\Databases\" & MasterControl.Text & ".mdb"
    Win32Script.RegWrite "HKEY_CURRENT_USER\Software\" & App.Title & "\CurrentSelectedItem", MasterControl.Text
    rs.Open RecordSource, ConnectionString, adOpenKeyset, adLockOptimistic
    If rs.BOF = False Then
        rs.MoveFirst
    End If
    For i = 1 To rs.RecordCount
        If rs.EOF = True Then Exit For
        OrganizerDatabase.ListItems.Add , , rs!SiteName
        rs.MoveNext
    Next i
    Set fso = Nothing
    Set rs = Nothing
    Set Win32Script = Nothing
    Exit Sub
ErrorHandler:
    MsgBox "Error #" & Err.Number & ":  " & Err.Description, vbCritical, "Program Error"
    Exit Sub
End Sub

Try this at the end and see what happens.

Dim intSave As Integer
intSave = MyCombo.ListIndex
Set Win32Script = Nothing
MyCombo.ListIndex = intSave

That code results in an error "Out of stack space" in my recordset opening routine.

rs.Open RecordSource, ConnectionString, adOpenKeyset, adLockOptimistic

Take the code out, the error goes away. I ran a quick Google search on the issue, and it says the limits of the stack have been exceeded, and to try declaring the variables inside a module, so I'll try that and see what happens.

Nope, it's not working. The combo box deletes its text right where I thought it was doing it - after I exit the sub. It's weird, because I don't have it programmed to do anything after it exits the sub, it's like this program's got a mind of its own. :D After a little debugging, I found out something is physically changing the contents of the combo box. (I put in a MsgBox call to see if the _Change event triggers, and sure enough it does.)
