Marking PowerPoint 2007 Presentations as Final

Do you move your slide objects by mistake? Maybe that chart moved up a few nudges due to an oversensitive mouse, or you pressed the arrow keys on the keyboard when a text box was selected? Or maybe you don't want to edit a presentation even by mistake once everything is final.

You're in luck if you use PowerPoint 2007 -- just choose Office Button| Prepare | Mark as Final, and your presentation is now read-only and cannot be edited. If you save the file with a new name, it still cannot be edited.

But if you choose Office Button | Prepare | Mark as Final again, the presentation toggles back to its original status, and you can make all the edits you want. Once you are done making the edits, mark it as final again.

For sure, this is not as good as password protection against edits -- but it's great for those occasions when you or someone else might edit the presentation by mistake.
