Issue Details

I have a VI that suddenly stopped allowing the Front Panel Indicators to update. If I do "Highlight Execution" and add probes, I see that all the values are correct, but are not getting to the front panel.. As far as I know, I have not made any changes that caused this. Some of my subvis are showing the same behavior, but not all of them. When I create a new test VI, everything works as expected. 

Solution

Sometimes a VI can become corrupt. You have several options for fixing this kind of behavior.
  • If you have a previous version of the VI, test to see if that behavior is happening in the old version. It may be helpful to revert to a previous version of the program.
  • Copy and paste the block diagram into a new VI. This will sometimes repair strange behavior.
  • Try a Mass Compile or Force Recompile
