As a side note, I did that ME works fine on Word Doc files as long as the replace string is the same length, otherwise the DOC is corrupted.[/quote:oafo1prc]
What else would you expect? DOC is proprietary binary format consisting from stored objects. I don’t know details but it is very easy to imagine if you change embedded string size following objects couldn’t be restored. It is the same as if you do it in the executable.
Using MEW for this purpose is IMO horrible idea. Why don’t you use proper tools i.e. Word itself?
