Why does my program run fine in highlight execution, but not normally?

[BoilerUp81]

Hey everyone,

So I created a program which works fine (producing an intensity graph) when I highlight excecution, but then when I run the program without the highlight execution, the output intensity graph does not appear. I have attached a copy of my program for reference. Thanks in advance for the help!

What type of error are you seeing? What is not working?

I don't have any of the subVIs that comprise your VI that you posted so it would be difficult to say what is happening but I suspect you are running into some sort of timing issue. When you run with execution highlighting turned on you slow the execution way down. When running normal things may run before the system is ready. Perhaps your camera initialization takes time to complete (on the hardware itself) and when you run in the normal mode you are trying to access it before it is ready.

2nd what Mark said. You probably have a timing/dataflow problem.
