COM and threads

HI all,

I have a problem in accesing COM objects in threads. To be precise,
lets assume that I have a class GenericFunctions which is defined as
follows:

import win32com.client, pythoncom, thread
ie=win32com.client.Dispatch('internetexplorer.appl ication')
ie.Visible=1

class GenericFunctions:

def __init__(self):
print "In Constructor of Generic Functions"

def MyNavigate(self,dest):
ie.Navigate(dest)
Now there is another file Main.py which is defined as follows:

import win32com.client, pythoncom, thread
from GenericFunctions import *
obj = GenericFunctions()

class Mainclass:
def __init__(self);
print "In Constructor of Main class"

def threadFunction(self,dest):
pythoncom.CoInitialize()
d=pythoncom.CoGetInterfaceAndReleaseStream(s,
pythoncom.IID_IDispatch)
my_ie=win32com.client.Dispatch(d)
obj.func(dest) # this is gving an error.
pythoncom.CoUninitialize()

if __name__ == "__main__":

s=pythoncom.CoMarshalInterThreadInterfaceInStream( pythoncom.IID_IDispatch,ie)
thread.start_new_thread(self.nav, (s,'www.google.com')

Basically, I want to access object of GenericFunctions class inside
threadFunction(). However I was able to execute
my_ie.Navigate("google.com"). But that was not I wanted. I am not
knowing where the error is....
Please let me know the solution ASAP...
