common dialog does not auto refresh its file list view

[Cubitus]

In my application I have a preferences dialog callable by the main form's menu. On the preferences form there's a button for selecting the app's log file.
I'm using a common dialog control for that task and found a strange behaviour on WinXP:
[ul]
[li]the dialog allows to create new folders
[green] OK[/green][/li]
[li]the dialog allows to delete folders/files
[green] OK[/green][/li]
[li]newly created folders are invisible within the dialog's file list view until the user presses F5 to refresh the view
[red] Not as in other programs on same computer[/red][/li]
[li]deleted folders/files will not vanish within the dialog's file list view until the user presses F5 to refresh the view
[red] Not as in other programs on same computer[/red][/li]
[/ul]

It does not seem to matter if the preferences form is modal or modeless.

Private Sub cmdAGLogFile_Click()
  Dim fsoTmp As New Scripting.FileSystemObject
  Me.dlgFile.flags = cdlOFNExplorer Or cdlOFNHideReadOnly
  Me.dlgFile.DefaultExt = ".log"
  Me.dlgFile.Filter = ""
  Me.dlgFile.InitDir = fsoTmp.GetParentFolderName(Me.txtAGLogFile.text)
  Me.dlgFile.FileName = fsoTmp.GetFileName(Me.txtAGLogFile.text)
  Me.dlgFile.DialogTitle = "Select Log File"

  On Error Resume Next
  Err.Clear
  Me.dlgFile.ShowSave
  If Err.number = 0 Then
    Me.txtAGLogFile.text = Me.dlgFile.FileName
  End If
  
End Sub

Any hints how I could get the (seems so) default behaviour of the common dialog in my app, too?
