>I check the code ( isn't mine) and I find out that this a very simple app opens the dbc and then the needed tables (no cursors, no views) and at the long on the apps append a record in the logusers table and then is whe it happens, the code is a simple serie of replace statements...

Another thing to check is if the database container or the tables are corrupted. It looks like you have a lot of respones... :-)
