This will remove all records for which both the abbreviation and name are blank
This message occurs in the Special Fonts Manager when you select the menu option Remove Blanks. It asks for your confirmation that you want to let Q++ automatically remove any record of the displayed font for which both the abbreviation and name are blank. This message also draws your attention to other methods of removing blank records which are not as drastic as letting Q++ do it automatically.
