It might be better to ask Microsoft tech support about this message if this is such an uncommon occurrence as it seems to be and they didn't publish about it in their Knowledge base.

I am running Vista and in the last five days I have noticed that this message is appearing in the list of the Event Log each time I open the application.
This Event ID 32 message is the last message that appears under Application Log.
Does anybody have a hint on how to stop it from appearing ?
