Hello Pauldj54,
First, what operating system and version of CVI are you using?
Do you see the same behavior with a release executable?
Also are you able to create a debuggable executable from the shipping examples and connect to the DataSocket server?
The basic datasocket examples are located in ..\National Instruments\CVI71\samples\datasocket\reader
and ...\National Instruments\CVI71\samples\datasocket\writer.
Thanks.
