It is typically a really bad idea to block the main loop with long delays. Right now, the VI is unresponsive for extended time periods and cannot be stopped.

It would be easy to re-architect the code without changing the basic operations. Even if it is working perfectly, it does not mean that the code is perfect. 😄
A dumb bandaid solution would be to place diagram constants and write to local variables of the progress bar in each frame.
