comtypes uses fairly extensive logging calls in certain areas.  You can enable this
to find out the reason.  Here is a little code snippet that shows what happens on
my system when I call GetEvents() with Internet Explorer:

<code>
from comtypes.client import CreateObject, GetEvents
import logging
ie = CreateObject("InternetExplorer.Application")
logging.basicConfig(level=logging.DEBUG)
GetEvents(ie, sink=object())
<code/>

and here is the output:

You should run the snippet yourself and compare the output.
