Some ODBC drivers are not thread-safe and, by default, the Easysoft ODBC-ODBC Bridge server for Windows runs multi-threaded. This can cause a number of intermittent errors. Change the ODBC-ODBC Bridge server to run multi-process so that there is only ever one thread at a time in the ODBC driver. Refer to Why does my second connection to Microsoft Access hang for instructions on how to do this.
Run the ODBC-ODBC Bridge server multi-process if you're using these ODBC drivers: Microsoft Access, Freedom Intelligence, Navision, Margin Minder, TPS, and eMatrix.
