To personalize Extensions Strip, open Extensions Strip Control and click on the "Register this copy" button. In the dialog that appears, enter what you like into the name and/or company fields. There is no registration code for Extensions Strip. Instead of a code, a "trick" is used. The registration trick is: (1) Turn on balloon help. (2) Click three times in the code field while holding the option key down. (3) Click on the OK button.
