Why is sub-vi border flashing red and blue

[felt]

Labview 7.1: I have a sub-vi which will halt the process of a program. On execution, the program runs until that sub-vi structure (step 12 in the structure) is reached, and there it stops with a red and blue flashing border. I don't have any breakpoints established that I know of, and I'm not doing highlighted execution.

Simple question I'm sure, but what does the flashing red and blue border mean?

Very similar problem with an earlier sub-vi, where the program halts with a flashing black sub-vi. No idea what these mean. (new to 7.1..)

Thanks!

The breakpoint may not be as expected..

OPen the subVI and check to see if there is a red contour when it is not running.

If it is the case, use the brakepoint (pointer) and click onto a blank area inside the block diagram of the subVI. The red contour should dissappear.

Run the vi (main vi). See if it is okay.

Definitely looks like a breakpoint. Sometimes they occur by accident, especially after a few cups of strong coffee. 😉

Go to "Browse...Breakpoints". Anything interesting?

Yes, I agree it looks like a breakpoint - but NI's text on clearing a breakpoint must have been written by MicroSoft - lots of verbage and no help.

How does one clear a breakpoint? I don't find a "breakpoint tool" that can be dragged over the vi to clear the breakpoint.. Browse Breakpoints finds the breakpoint (thanks!) but no indication on clearing or removing the thing.

Thank you.

After much searching, I found that SHIFT right-click brought up a tools panel that allowed me to clear the breakpoint on that structure.

Thank you for your help.
