Hello Rafi,
First, I have a few questions for you to help troubleshoot this issue:
What is different between the development and the test machine? You mentioned you have CVI 7.0 on the development machine. Do you have the CVI development environment on the test machine, or just the runtime engine? If you run your application on the development machine outside of the CVI environment, do you see the same incorrect behavior? Also which version of the runtime engine and/or CVI are you using on the test machine? Is the operating system and service pack on the test machine the same as the one installed on the development machine?
Thanks.
