each hang generates both events

We then go to msft and follow all steps to uninstall IE since sp1 removes
the add remove program from the control panel its a manual operation. All
attempts to remove or repair fail. We then take the drastic step of
uninstalling SP! which is suppose to allow the add remove back to control
panel, it does not.

Open to suggestions: need to get IE uninstalled, reinstalled and SP1
reinstalled
