Halt VI when Wait Untill Done.VI is waiting

Question

This program is for digitally triggered analog acquisition - N samples,
N channels.
There are 2 loops, one for the acquisition and one for user controls
for the graphs. When the user presses the STOP button the VI will not
stop because the WaitUntilDone VI is still waiting for the next
trigger.(Therefore it will only stop after the next trigger) Is there
anyway to interupt the wait until done and halt the VI?
Another question: When I stop this VI using the STOP button(The one I
have put) and then run the VI again the 2nd loop(controls for the
graphs) does not execute!
I am attaching the 3 VIs used. The main VI is skeletonv4.1. The other 2
are used as sub VIs.
Thanks!

Answer 1

Loop 1 sets a local variable (X) to TRUE when it quits.
Loop 2 sees X = TRUE and quits.
You start the program again - BUT X IS STILL TRUE.
Loop 2 finishes before loop 1, sees X = TRUE and quits.
Loop 1 finishes, sets X = FALSE, but it's too late.
You need to set X FALSE, before either loop starts.
You are using code to set X.Visible to FALSE, you can do the same thing by popping up on the X terminal and choosing HIDE INDICATOR - you don't need code to do it.
