As the other response pointed out, you probably want to place a delay in your loops. And this seems odd at first, but if you can't afford to wait a whole ms, wire up a zero to the wait. This will cause the scheduler to rotate the round-robin execution queue and will cause smoother interleaving of tasks. Without this, the loops will often interleave at around 100ms increments, which has less overhead actually runs somewhat faster, but is more jerky. Greg McKaskle
