I've created an event receiver to handle the ItemAdded and ItemUpdating events on a document library in SharePoint 2010.

I've encountered a problem where when I add a document to the library (e.g. by saving it back from Word) the ItemAdded method is correctly called however this is then followed by two calls to ItemUpdating. I have removed all code from my handlers to ensure that it's not something I'm doing inside that is causing the problem. They literally look like:

public override void ItemUpdating(SPItemEventProperties properties)
{
}

public override void ItemAdded(SPItemEventProperties properties)
{
}

Does anyone have a solution to this issue?

Here is my elements.xml file for the event receiver:
