Identifying Automatic Changes

[Budge <ajebay errichel co uk>]

How may I determine what automatic changes are being made/proposed when 
after opening a file in Easytag and then leaving without making any 
changes intentionally, I am prompted to discard, save or cancel?

I suspect it may be the illegal character setting which I have just had 
to change in my preference setting because my NAS box insists on using 
the windoze broken character set even though we are all linux here.  Is 
there any easy way to check if this is the case?
