can't Undo after shutting down FCPx

Maybe I don't know enough here but is there a way to do an undo after coming back from shutting down the computer. I would think theres away to keep the undo cache so you can continue editing when you come back. any ideas?
thanks, randyc

The undo cache list is dumped when the application is closed.

Normal behavior for most apps. Very few retain any undo data once you quit them.

What Tom and Ben said, plus I will add: it's absolutely a good thing that the Undo cache gets flushed whenever you shut down the app. The Undo cache is stored in your RAM, so after working for many hours your RAM will get filled with Undo actions and - depending on the amount of RAM you have - your system may slow down. I have asked Apple numerous times to

1. Have an option to put a limit on the total amount of RAM FCP X can use (an option we do have in Motion)
2. Have an option to put a limit on the amount of Undo actions you can store
3. Have an option to flush the Undo cache inside the app

This would especially be helpful for people who work on systems with less than 16 GB RAM.

You don't really need to store that many Undo actions anyway.

- You can make regular Snapshots of your edit. Snapshots allow you to instantly get your edit back to the state in which it was when you made the Snapshot. Making regular Snapshots has become a standard procedure in our workflow and I wish we could manually flush the Undo cache whenever we have made a Snapshot.

- If you have shut down your app or your computer and you would like to go back to a previous state of your edit but you have made no Snapshots, and of course you cannot use Undo anymore, you can always try to restore your edit from the latest Backup. This will bring your edit back to the point where your last automatic Backup has been made. Backups usually get created every 15 minutes.
