My original problem was that during program development my program gets in to an unbreakable loop somewhere, and I have problems finding it since I have to shutdown labview each time it occurs. I'll try learn more about breakpoints, and restructure the program as suggested bye Joe.
I just made a test program, only a while loop with "false" as condition, that runs forever, but this program is easy to stop with the "abort execution" button. What is needed to make a labview program that doesn't respond to the "abort execution" button?
