Selection of the Data Panel radio button sets the Font dialog up with the current font of the Data Panel window. A user may then set another font in the Data Panel windows, if desired, by selecting the font, font attribute and size and pushing either the Apply or Save buttons. Any font applied with Data Panel selected is set in all Data Panel subwindows in one step.
To set the font for all Data Panel windows using the Font Palette, drop a font on the X: Used subwindow.
