On my system, it does not open more than one file at a time, and it does not overwrite a file with any part of another.

If something weird like that happened to you, I suggest you do Opt., Return to Factory Settings.

I can't comment on the Melodist - I don't use it.

NOTE: what do you have for the checkbox in Opt., Preferences at the bottom that says, "Allow multiple instances of BIAB to be running"?
