Unable to display results

[lihui]

Hi. I have a program that capture data results from gpib and then
display them using leds. When i run the program, 2 problems occur:
1)No results are displayed.
2)Display Front panel never pop out even though i set the VI execution
properties.
The funny thing is that when i monitor the program movement by running
it in steps, there isnt any error in the program and the results are
properly captured and displayed.
