spellchecker freezing

Hi I use the following bit of code for spellchecking in an access application.

VB Code:

Private Function Spellchecknew(TextStr As String) As String
 Dim WordApp As Word.Application
  
     Set WordApp = CreateObject("Word.Application")
    
     WordApp.Documents.Add
     Dim wordrange As Word.Range
     Set wordrange = WordApp.ActiveDocument.Range(0, 0)
     wordrange.Text = TextStr
     WordApp.Visible = True
     WordApp.Activate
     
     wordrange.CheckSpelling , , True
     wordrange.CheckGrammar
     Spellchecknew = wordrange.Text
      
     wordrange.Text = ""
     WordApp.Documents.Close (False)
 
     
     WordApp.Quit
     
     Set WordApp = Nothing
    'MsgBox "test"
 
End Function

It nearly allways hangs in Access for about 5 seconds after the above is run, so I tried to find out what was causing the delay, but if you include the msgbox "test" at the end, the program doesn't freeze, infact it works out quicker to keep the message box command in and then click okay, than it does to remove it.
Why would this be, and how could I dulicate this without using a message box. have tried things like me.repaint but it's still the same,
