My "save as" file gets undated when I save the the original file

[Edward23711649x97l]

I will do a "save as" with a different name and when I edit the original file that the "save as" file came from it changes the save as file too! Any ideas on why it is doing this. I have even tried three or four layers deep of Save As and it changes all of them.

I presume we are talking about Waveform view here? Is the file you've Saved As still open in the files menu?
