Unless you’ve made style changes, you can apply changes to your form guide at any time by clicking Apply on the Edit Guide tab. Clicking Save stores the form guide information within the original form design and saves the guide style as a SWC file relative to the form design file.
When you change style settings in the Customize Appearance tab, you must save your changes before you perform any other tasks. All style information is saved in a SWC file. If you move the form design file, you must maintain the same relative path to the SWC file.
After you apply and save your form guide changes, close Guide Builder. The changes to the form design in Designer ES are also saved when you save the form guide changes.
