Hi
I am writing an app that has to detect if a document has changed, so it can prompt to save or cancel.  I've tried using
.Content.Changed
.Content.ModifiedChanged
.document.Changed
.document.ModifiedChanged
None of them fire reliably as I type, paste, delete, cut.  The first one fires when moving a mouse over the control, or sometimes on a keypress but not always.  Can anyone point me towards what I'm missing?
