closing specific powerpoint presentations

[Scrooby]

Hi,

We need to close some specific powerpoint presentations from another powerpoint presentation (leaving this presentation open and active). We tried some codes (see below), which worked really well on PPT97 & Win 2000, but failed to work on PPT2003 & WinXP :S!!
Can somebody help to make this code work on all computer environments?

The code we used:

  Dim aa As Presentation
  For Each aa In Application.Presentations
      With aa
        Select Case .Name
          Case "Presentation1", "Presentation2", "Presentation3"
                   .Close
        End Select
      End With
    Next aa

Thanks, Huib
