I have suddenly encountered a problem running MPLAB 6.40 on my Toshiba laptop under Win98se. It has previously run fine but now hangs with a "Not Responding" condition while displaying the Microchip logo screen. I've uninstalled MPLAB and reinstalled it with no change in symptoms. Has anybody else seen this occur? Any ideas out there? Thanks, Bob -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
