Curiously, that didn't work. This did:

    #ifdef LINUX
      pthread_t thread1;
      threadHandle = pthread_create(&thread1, 0, (void *)fltkRun, (void
*)NULL);
    #endif

But I know not what I do. I basically copied some example code from the
net, plugged it in, and voila, it works. That's mojo, not programming,
so I'd like to know some why's and wherefore's.

Any comments ? I'm a total novice at threads, I'm studying some tutorial
material on the net, but I don't understand why Paul's suggested code
didn't work.
