Well it sure appears your pic is configured correctly, I think. Do you have OSC in your code? what version of PBP are you using? I remember something about OSC messing with something in some of the 18's when using 2.6C, but don't know the fix or if it applies to the pic you are using, But there is a fix if thats what it is.

So do you think the pic is running at 32?
