I opened two different backups of the same wallet in notepad. Why are they different? Wouldn't they be exactly the same file if all they contain is the private key?
I may be mistaken here, but I think it also contains other info on the addresses your using etc. Have you added an address or anything between backups?

No, and in fact Blockchain sent me another automatic backup that has yet another series of letters and numbers. I imported all of them to my wallet at Blockchain and it did nothing as I expected. But I don't understand why I have three different backups now.
