There are several resources you can use to affect the way help is displayed.
By default, graphical Prism uses the Netscape browser to display help information; see " Using the Browser-based Help System". Set the Prism.helpBrowser resource to the executable name of another browser to start; the name must be on your path. Graphical Prism supports Mosaic and Netscape browsers. You can include in the setting any browser-specific options that you want passed to the browser when Prism starts it up. (Note that these options do not take effect if Prism uses an existing browser; see below.)
If you already have a browser running when you request help from Prism, by default Prism displays the help information in this browser. Set the resource Prism.helpUseExisting to false if you want Prism to start a new browser. Set it to true to return to the default behavior.
