I cannot reproduce the problem. We have around 200 installations and this problem occurs a couple of times a day.

Looking in the DataExpress Database class the connection is created this way:
connection = DriverManager.getConnection(cDesc.getConnectionURL(), properties);
The DataBase class is long. If you want the source code I can send it to you.

I think I found a way to replace the jdbc connection in the DataExpress DataBase object. Will try it in action.
