let's have a minute of silence to bye to this poor PIC who left us after many many many good hours service.

As now, i never get this problem. When i finish a project, i change the PIC and keep a copy of the finish PCB with the PIC used to develop it.

Only a few time i get that kind of problem. As i suspect, it was caused by floating unused pin and/or circuit modification when power is on... not a good practice
