Thanks everyone. I'll try that in a couple hours, but you are probably correct. I was migrating from a 16F54, which didn't have analog options on the pins I was using, so when I was updating all the registers, I didn't think about adding new registers. I'm pretty sure you guys are correct though. I did have MCLR tied high. There must be some analog conversion going on that causes the unit to reset and somehow the pauseus command is enough to prevent it, but it isn't worth investigating if going digital cleans it all up.

Thanks again.
