I use Win7-64. My keyboard is an old, old IBM Model M, made in 1989 [don't laugh, it works perfectly and I love it; I hate the quiet, mushy ones and have never found a use for the Windows key]. However, in the past couple of weeks, the ESC key has stopped working. Of course, I initially chalked it up to an ancient keyboard giving up the ghost, but I swapped it out for another I had and, once again, the ESC key is the only one not recognized. I haven't downloaded any new drivers (unless there's one in the normal Microsoft updates). So far, anything needing ESC has offered an alternative means of dismissal, but one day my luck will run out. Any ideas?
