Setup: Xydos 4.018, using 4-3 kbd file. Recently reinstalled both Xywrite printer file and printer driver (NECSS860).. Computer is 633 mHz PC, 64 MB RAM with AT keyboard. Sudden new problem: lower-case key 40 produces double strike when followed by another character (e.g. "she's" or "they'd"), but not when followed by a space. Tests reveal that lower-case key 1 (`) and upper-case key 7 (^) do the same thing, but other keys do not.
