The User Preferences window is accessed in the Main Display window through the Edit->Preferences menu. The Data Sources tab allows the user to define what types of data choosers to use. This is a way to simplify the Data Explorer window by only showing the choosers that you want to use. Note that you must restart McIDAS-V for any changes made in this tab to take effect. The image below represents the default settings for the Toolbar Options tab.
