Error message: Exception error within external code

[Ashley.w]

Hi

I am getting an error message on running one of my vi's that uses DAQ.mx that causes labview to close it reads:

An exception occurred within the external code called by call library node.  This might have corrupted LabVIEW's memory.  Save any work to a new location and restart LabVIEW.  "VI ......." was stopped at node OX19E4 DAQmx Start Task.vi.

The odd thing is if I put execution highlighting on the vi runs ok and then continues to run OK untill I close Labview and restart it.

Is anybody familiar with this error.

Many Thanks.

Ashley

I've never come across this error before but looks to be a problem with the NI-DAQmx driver. As a first step, I would recommend unisntalling the driver and then re-installing (i would also install the latest version 8.0).

Funny how slowing the code down doesn't present the problem. let me know how you get on with the above.
