When a text selection is set, the selected text is redrawn using selected-highlight color when the textbox loses focus. This convenience feature shows the active text selection as you move the pointer to the new target window. When a new selection is set anywhere else on your screen, the current text selection will be redrawn using the inactive-highlight color as the textbox loses selection ownership. In most CINELERRA-GG themes, the drag selection text-highlight color is BLUE (#0000FF), the selected-highlight color is SLBLUE (#6040C0) – really sort of purple, and the inactive-highlight color is MEGREY (#AFAFAF).
