If you double click on the line spacing indicator under the ruler bar in ClarisWorks 4.0 for Macintosh, you will be presented with the Paragraph dialog box. You can change the line spacing from lines to points or another unit, and change the unit value for the line spacing. If you change the unit measurement without also changing unit value, the line spacing indicator in the ruler bar doesn't reflect this change, even after clicking OK or Apply. To get the change to be reflected by the line spacing indicator press the Tab key, click the Align pop-up menu in the Paragraph dialog box or actually change one of the unit values in the line spacing boxes before clicking OK or Apply.
