    Hmmm... Sougata's point about starting timer1 sounds like it might be the culprit, at least as far as RC1 going to input. PWM2 drives a fan via a MOSFET, so if RC1 goes to input, the pullup I have on the MOSFET would drive the fan to full speed, which is exactly what's happening. I haven't yet found in the data sheet why turning timer1 on does that to RC1.

    I have attached the code relevant to Darrel's question. The INCLUDE files that aren't attached don't modify the registers Darrel was talking about. I have very little experience with using the timers or using interrupts-- is it possible to just modify the Elapsed Timer routine to use timer 0 or timer3?

    Thanks--
