Hi there
If what you are asking is if there is a way to configure all users so they have identical preferences, you might try this:
From any account on the computer, open Captivate. Click Edit > Preferences and ensure the settings are pointing to a common location shared by all accounts on the computer. Dismiss preferences.
Now click File > Export > Preferences... and save them to a file in a known location that is also shared by all accounts.
Now open each of the other accounts on the computer, start Captivate and click File > Import > Preferences... and see if things are configured accordingly. If so, repeat the process for all accounts on the computer.
Cheers... Rick
