>- Setting all fields' lostfocus is a good idea but what will happen if the table is reverted (rec or table). And won't it slow down the app.

If you revert the table, then you revert the log table at the same time. It's not going to slow down the app enough to worry about, because the code will only fire if the field value has changed.

>- Datetime doesn't help either. I cannot be sure that one entry is made later just by checking the datetime. What if one computers time is 40 minutes apart from another.

At some point, the clients/users will have to take responsibility for their data. We HAVE included a time-adjustment which allows for time zone differences.

>Instead of field level I planned to put logging into update, delete, insert triggers. This doesn't help either if any particular record is edited or deleted in more than one location.

This is fine, if your tables are small enough that uploading/downloading all the tables is not prohibitive.
