Getting exceptions when catching events while
interacting with InternetExplorer.Application.

Class connects to IE via

self.ie =
DispatchWithEvents("InternetExplorer.Application",
InternetExplorerEvents)

Subsequent events on some (not all) URLs cause
exceptions as follows:

pythoncom error: Python error invoking COM method.

URL being accessed via 

        self.ie.Navigate( url )

A number of URLs lead to the behavior including the
following:

http://www.cnb.com:80/
http://www.cnb1.com:80/
http://www.charterbankcc.com:80/
http://www.charterbankec.com:80/

I can provide test code if it is helpful.

The following url reproduces multiple instances of the behavior:

http://www.clever.net/kerry/scuba/main.htm

The browser should be configured to allow popups.

Since it's a problem with the win32 extensions which aren't
part of the official Python distribution, please report this
to ActiveState or the Pywin32 maintainer.
