For the Preferences -> Calendar -> Display
page, these options are used only if you have not logged on to the system for more than 15 days. If you log on more frequently, the options selected before log off are used when you log on again.
For example, on the Preferences -> Calendar -> Display page, you might set the default view to Day view. However, this preference setting is ignored if you log on daily and view the calendar with a weekly view. The weekly view becomes the default view. The Day view preference is used only if the customer logs off for more than 15 days.
