that is what i thought. I have a generic database book that is used at most
universities that says its optimal to apply undo before redo. trying to figure out where it is coming from.

That doesn't make much sense, does it?

When you create the data, you create undo, then redo from the undo.

You can't recreate the undo without the redo.

( we're well on our way to a world class tongue twister )
