humm... If you can find the hWnd of the Word document, you can use the SetWindowLong API as follows:

Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long

Private Const GWL_STYLE = (-16)
Private Const WS_CLIPCHILDREN = &H2000000
Private Const WS_CLIPSIBLINGS = &H4000000
Private Const WS_OVERLAPPED = &H0&
Private Const WS_VISIBLE = &H10000000

' some where in code
SetWindowLong WordDocHWnd, GWL_STYLE, WS_CLIPCHILDREN Or WS_CLIPSIBLINGS Or WS_OVERLAPPED Or WS_VISIBLE
End Sub

this will hide the title bar. but you need to find the hwnd of the document window first, I don't know how to do that off the top of my head.
