Help me. How to open a new IE window?

[angel]

Hi

I want python(win32com) to open a new IE window.
Source is:
/******/
import win32com.client
msie = win32com.client.Dispatch("InternetExplorer.Application")
msie.Visible = 1
msie.Naviagte(http://www.python.org)
/******/
The problem is the program always grabs a existed IExplorer window or
Explorer window. It never opens a new window.

Please help me. Thanx
Victor
