hello, in office 2003, if you did document1.Merge(document2) it would report a line that is in document1 but not in document2 as inserted, and a line that is in document2 but not in document1 as deleted. i.e. it would assume that document1 is the "new" document and document2 is the "old" document. in office 2007 it is almost always the other way round i.e. assumes document1 is the old and document2 is the new (AFAICR this is the same as previous versions of office before 2003 used to do) no problem so far, I just detect in my application (c# .net 2.0 FWIW) which version of word I am connected to, and set the sense of the comparison accordingly HOWEVER, under office 2007, for some pairs of documents, I get the same result regardless of whether I call: document1.Merge(document2) or document2.Merge(document1) I.E. word 2007 is "intelligently" deciding which is the "new" and which is the "old". from my experiments it does not seem that this has to do with the file time stamp or the 'last saved' property. Does anyone know how word 2007 decides which is the newer document and if there is any way I can override it to force the sense of the comparison. TIA Andy
