To change the look of the dialog windows:
1. From the main menu in Flash select Window -> Common Libraries -> fCMSProAssets. This will open a library containing several movie clips for the fCMSPro.

2. Ensure the the library for your current movie is open (CTRL+L) and drag the fcmsDialogs movieclip from the fCMSProAssets library, into the main library for your movie.
3. You can now edit the dialog windows by editing the fcmsDialogs movie clip that you just dragged into your library. You will notice that there are keyframes on the timeline of this movie clip which show the various dialog windows: password, badLogin, saveChanges, alert. You can change the layout of any of the fCMSPro dialog windows, however you must ensure that you do not change the instance names of dialog elements.
