Cetin,
I tried implementing an error handler. But VFP ignores the handler, says that the record is in use by another, and I when I press either cancel or ignore, the application ends. This happens when the second user attempts an edit of the field that the first user is editing. I tried setting readonly to true and that didn't work. I hate to abandon the grid interface for editing, but can't seem to stop the application from exiting. But thanks for you help.
