Well, that just totally stinks. I had been wondering about why the ID numbers changed suddenly. I maintain an off-line (private) database for my own personal use. I laboriously changed all the numbers by hand to match the "new" ID numbers. Now I find that they aren't ID numbers at all. *SIGH* My database has 4,000 records in it! Gee, I wish I had made a backup before I started changing all of them . . . or used a new field . . . or something. Crickey.
