Hi,
I am using USB 6225 to do some AI/DI data acquisition. When I added DIs and stop acquisition SignalExpress sometimes sits in "Stopping" state and does not stop.
This one was run for 40-60s and then I hit stop. Since then it is still in "Stopping" state. this only occurred when DI acquisition step was added with sample clock "Change detection".
Same thing happened with just the DI channels added with "Acquire" not selected:

I noticed that exact same problem occurs when I create a NI-DAQmx Task in MAX to log data from P0.0-P0.7 on "Change detection". I enabled TDMS logging, set a file and hit run. When I hit stop it changes button to Abort and never stops:
Task with Analogue voltage read works fine. Stops and show plot:
