Acrobat User Community Forums

Hi kspangler,

First, you should understand that Acrobat 8 Professional and LiveCycle Designer are two completely separate programs.  Yes, they come in the same box, but they are separate entities with different User Interface options.  This is a common source of confusion regarding these two products.
In Acrobat 8 Professional you can set a time interval for saving a file while working on it in Edit ->Preferences -> General- "Automatically Save Document Changes to Temporary file every X minutes."
Unfortunately, LiveCycle Designer does not have an incremental save feature.  You can go to Tools ->Options and check the box "Create Backup on Save," but that is about it. The best you can do is make it a practice to do frequent incremental saves manually.

Hope that helps,
