Hi, my Flash documents keep changing when I reopen them. For example, I change a shape's color from white to orange and then save the document. I then reopen the document a day later and the shape is white again.

I definitely save the file each time.

How do libraries work in Flash CS 5.5? For example if I open an older version of a project e.g. myproject1.FLA, and then open the current version (myproject5.fla) will the opening of the older version overwrite the elements in the library?

It is a bit of a mystery.
