Hello All, My name is gil and I have a problem. I have customer specifications that force me to use event case and a while loop uner the same parent while loop The codes must work in such a way: the while loop is connected after the event case so after the event case has reached the "Timeout" event, the next loop will statr working until it is stopped and then again to the event structure. - as can be seen in file1. The reason behind this is that the coustomre has already built events that both update the GUI and communicate with the hardware. I have tested this configuration seperatly and It works rather well. When implementing this code in the version. all of the controls become unresponsive and I cannot do anything. I have placed a probe on the index of while that runs after the the event case, And I can see the number of itteration is growing, i.e. the program is running. I cannot attached the original code due to proprietary issues. but I have attached a code the mimics the logic. Can anyone please tell me why the system become unresponsive? Thanks! Gil,

LabVIEW

In the defense of the OP it seems to be a work in progress of a simulation of a problem enforced by a 3rd party for reasons unknown...

Not the easiest way to learn LabVIEW.
