The Office 2007 interop API doesn't provide any event on document changes.
How can i get an event for each modification that happens ? (like OnDeleteSlide, OnAddSlide, etc..)
I think to get a hash of the document actually in ram, but don't see how...
Maybe check the state of the crtl+z control...
Word.Application.DocumentChange +=new ApplicationEvents2_DocumentChangeEventHandler(...);
