Wayne,
Are you logging in as admin? When I say that, I don't mean going to the main screen and selecting View and Administrator Options or using CTRL + A. I mean actually logging into Amazing Charts as the admin.
At the window where you choose your name in the drop down box and then type in your password, don't choose any user. Instead, type in "ADMIN" without the quotes, enter the admin password and select Log In. You will now see yourself in the admin window but WITHOUT Amazing Charts being open.
Now, select "Set Prescription Format" and set your twips. Choose "Save Prescription Preferences, and you are all set.
To test it, go back to the Set Prescription Format and you will see that your twips are saved.
