Just an FYI for everyone. I was testing some simple delay routines with SIM=20 in MPLAB 6.10 this weekend, and the stopwatch gave=20 some really weird results. Stepping into the delay routines gave good results, but stepping over the routine usually showed very LONG delays, many times more than were actually used. I repeated the test many times, with the same results. I am confident that the problem really is in SIM, and not in my code.
