Problem with DispatchWithEvents

[ccahoon]

Traceback (most recent call last):
  File "windowedfax.py", line 223, in OnClick
    self.iexplore = DispatchWithEvents("InternetExplorer.Application",
eventHandling)
  File "C:\Python24\Lib\site-packages\win32com\client\__init__.py",
line 268, in DispatchWithEvents
    user_event_class.__init__(instance)
  File "windowedfax.py", line 178, in __init__
    this.iexploreInstance = self
NameError: global name 'this' is not defined

Output completed (18 sec consumed) - Normal Termination

I am running Python 2.4 with the most recent 2.4 win32all package
installed.  This is straight from the installer.  I did a clean
installation of everything.

This was working before I tried an ActivePython distribution.  It
stopped working because ActivePython did not seem to support my SSL
usage in urllib, so I returned to a stock python distribution.

The line where I call DispatchWithEvents is like this:
iexplore = DispatchWithEvents("InternetExplorer.Application",
eventHandling)

where eventHandling is a functioning class to that purpose.

Thanks for any help, in advance.
