For several years I found that the ICD2 only worked RELIABLY on MPLAB 7.4 or 7.6. On an accidental venture while chasing something else, I discovered that MPLAB8.36 again reliably uses ICD2s. Give Microchip a cheer. Whatever was wrong is now fixed. --Bob -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
