>well, I see, once again, I am the only guy with problems. Nobody else >seems to have any... I happened to be looking at the errata sheet for the 16f627A/628A/648A yesterday, and noticed EEPROM problems that look like they could be related to what you see, for some revisions of the chips. Might pay to look at it, and see if there is similar for the chips you are using. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
