[python-win32] Error in word with AddTextbox

[Sylvain Fauveau]

Hi.
 
I'm trying to add a textbox in word with python 2.7 / pywin 220 Under Windows Server 2008.
 
from win32com.client import Dispatch, constants
word = Dispatch('Word.Application')
document = word.Documents.Add()
orientation = constants.wdTextOrientationHorizontal
left = 100
top = 100
width = 200
height=100
document.Shapes.AddTextbox(orientation, left, top, width, height)

This give me this error:
Traceback (most recent call last):
  File "add_textbox.py", line 10, in <module>
    document.Shapes.AddTextbox(orientation, left, top, width, height)
  File "c:\usr\python27\lib\site-packages\win32com\gen_py\00020905-0000-0000-C000-000000000046x0x8x5.py", line 21712, in AddTextbox
    , Left, Top, Width, Height, Anchor
pywintypes.com_error: (-2147352567, 'Une exception s'est produite.', (0, None, u'La valeur tapee est en dehors des limites.', None, 0, -2147024809), None)

(A value typed is off limits)

I have absolutely no idea why this example doesn't work.
All the args of the AddTextbox method are not optionnal.

If someone had an idea...

Thanks in advance
