There are several customizable settings for displaying 3D globe PMFs. These settings can be accessed through the 3D Data View tab on the Tools Options dialog box. Settings include displaying a north arrow, stopping navigation at the globe surface, showing a heads up display, showing globe tips, and controlling the level of detail displayed.
The settings are stored in the ArcReader template file. The template, ArcReader, is located in \Documents and Settings\<user>\Application Data\ESRI\ArcReader\Templates. If you remove the template file, ArcReader will start with the default settings. The ArcReader.art file is created or updated each time you exit ArcReader.
