addin with eclipse integration

[SomersetGraham]

Hi
I have an addin that implements the EA_OnNotifyContextItemModified method
I also use the eclipse integration.
In standalone mode my addin is called when I open the properties for a class and press the 'OK' button,
However, when i use the eclipse integration this method is repeatedly called, even without the class properties window open.

Does anyone know what might be causing this behaviour?

Thanks
