Users have reported that after installing Acrobat 7 that changes made
to normal.dot are not being saved.  One of the posters confirmed that
Shift+File>SaveAll before closing Word resolved his problem.  I am
wonder if the following AutoExit would work?  I don't have Acrobate 7
(open to donations) so I can't test it here.

Sub AutoExit()
'Place this macro in Normal and other document templates
Dim myTemplate As Template
Dim myString As String
Dim oChgAlert As Balloon
Set myTemplate = ActiveDocument.AttachedTemplat­e
myString = myTemplate.Name
 If myTemplate.Saved = False Then
   Set oChgAlert = Assistant.NewBalloon
   With oChgAlert
     .Heading = "Microsoft Word Alert!!"
     .Text = "Changes have been made that effect the" _
             & " Global template, " & myString & ". Do you want" _
             & " to save these changes?"
     .Button = msoButtonSetYesNo
     .Animation = msoAnimationGetAttentionMinor
     If .Show = msoBalloonButtonYes Then
       myTemplate.Save
     End If
   End With
 End If
End Sub
