unable to refresh document window from Word vba

[Clif McIrvin]

I just discovered that there is some discussion of Word vba here.
In Excel, I am used to being able to turn screen updating on and off, and programmatically trigging screen refresh at will.
Working with Word vba I have found what should be the appropriate commands; but I cannot make the screen refresh while my code is running.
For instance- this code snippet:

Set r = Selection.Range 'begin search at user selected location
r.Expand wdSentence
Application.ScreenUpdating = False
ActiveWindow.ScrollIntoView r
Application.ScreenUpdating = True
DoEvents

varText = "Build Sub/Function headings?" & vbCrLf & _
   "Is " & r.Text & vbCrLf & _
   "where the search should begin?"
 
Select Case MsgBox(varText, vbYesNoCancel, "Mark Sub/Function Headings")

does not refresh the screen until my code has finished running.
I have also tried

Application.ScreenRefresh

What I am trying to do is to have the document window scroll to the correct position before the MsgBox displays.
Suggestions?
