No, you main problem was (and still is) the fact that you place "infinite" loops inside event structures, blocking all other events. New events cannot execute unless the current event finishes! For lack of a better word, your code suffers from severe constipation. 😉

You also duplicate the entire case code, if in fact the only difference is the "+1" vs. "-1". This is very inefficient, since it also forces the use of local variables.

The easiest solution is to use the outer loop only as I demonstrated in my second example. Here is a quick modification that also implements the down counting. (LabVIEW 7.0). Notice that all events immediately execute, event in you would set the count interval to minutes or hours.

There are other solutions, but they will be more complicated and would involve multiple independent while loops.

Correction: In my above example I mislabeled the boolean text on the down button. Also, in the reset case, the timeout should be set to -1. Modify as needed.
