I'll have to check to see if I tried running it true programmed mode vs debug "run".  I know the timers all stop running while asleep, and thats ok, they will come back out and start running once it wakes up.  Its a matter of it waking and actually running. I've done sleep before in the 16F913 without any problems, but I woke it on a change of PORTB, but an interupt is an interupt, once they are set up correctly.
