You need to make sure that the configuration is actually what you think it is. I suspect that's where the problem may lie. Your guys/gals could have made a mistake, and also it could be that the #include file for that processor has an error in it or something else equally simple or silly. Note that the default/erased mode is that /MCLR is enabled, so any error in configuration will tend to leave it in that mode. Best regards, Spehro Pefhany --"it's the network..."
