My Data acquistion Scan locks up until I move the Mouse

[Fridge]

I have set up a data acquisition Scan and am using a while loop to read the data. Every so often the scan will just stop, like its no longer getting points and the program will just sit there. As soon as the mouse is moved, however, it picks right back up again. This effect just started happening when I upgraded the software from Labwindows 5.0 to 6.0. What could be causing this and how can I fix it.

How can you tell that the scan stops? Are you plotting the analog input data to a graph? Does the graph just stop updating?

Why don't you add something like add a timer to your program that is continually incrementing to see if that locks as well.

I have a real time graph that plots when the DAQ buffer reaches 120 points which in this case is every second. The plot actually stops updating until the mouse is moved. This doesn't happen every test, just once in a while.
