I am not able to reproduce this issue with the version of DataSocket that I have on my machine. What version of the DataSocket Server Manager are you running? You can see the version if you click on About DataSocket Server Manager from the Help menu. Also, DataSocket Server Manager saves its settings in the cwdssini.dss file in the DataSocket installation folder. The problem you're describing could happen if this file is read-only, so check attributes of this file.
