Denny,
Which controller and OS are you using? Also, could you tell me which version of MAX and NI-IMAQ you have. You can find the version number of NI-IMAQ under the software folder in MAX. As a general practice, it would be a good idea to make sure you have the latest driver version, which currently is 2.5.3.
