I had a bit of a crash, and had to reload Nigel Goodwin's wpicprog2. I'm using DonTronic's DT001 with a DT101 and Mplab's editor. I now notice, (which I'm sure didn't appear before) at the end of the programming action, there is a very, very, brief message "Blowing fuses to 0x11" It then displays the time taken, as usual, and exits, as usual, and the programmed PIC seems to work OK. "Seems" being the operative word! Is there a problem lurking therewithin, just waiting to bite me down the track? Suggestions would be appreciated, as would a pointer to information on the subject of fuses, which has now been brought to my attention. Thank you all. Howard.
