>Chris,
>In addition to Bruce' suggestions, open your project data tab and highlight the problem table. At the bottom of the project it will show the path it is using for that table. Is it possible you're fixing copy A while the DBC is looking at copy B?

Good idea - and also (especially if table not in project), do the same for the for the table, look at path on the "Table" page when in MODI STRU of table. If all these things pass muster, probably the problem is in the app code somewhere, and not the project/dbc...
