threading and internet explorer com

[Stefan Schukat]

... and pythoncom.CoUninitialize()

My preferred way is:

def run():
	pythoncom.CoInitialize()
	try:
		ie =
win32com.client.Dispatch('InternetExplorer.Application.1')
	finally:
		# Trigger the release of the object since after
CoUninitialize
		# it could not be reached
		ie = None
		pythoncom.CoUninitialize()

	Stefan
