This sounds like you could have a possible rise time issue on the power supply. How are you powering your circuitry? Do you have longish jumper leads? Too much inductance (long wires) and/or too much capacitance (big caps on the power pins) can lead to slow rise times on the voltage. Allot of circuitry can be picky about this, including PICs. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
