HI - Somehow I seem to have accidentally selected every other row in every account register to display as black. Was working away, all was find, began a One-Step Update, when suddenly on the main screen behind the OSU, my register display changed as described. Have checked register settings including global settings. Have closed & reopened Q. Have restarted computer. Have discovered (by accident) that pressing Ctrl and clicking on a line temporarily "un-blacks" the line - i.e., makes it visible again - [Removed - Profanity] Ideas?
