This one kind of cheesed me off this morning.
When I create a constant/control from a terminal on a primitive I have come to expect the value to be the default value. Those tricky folks found a way to get me again.
Drop a Wait on Occurrence onto the BD
Right-Click on 'Create Control' or 'Create Constant' from the suggestively named 'ms timeout (-1)' terminal
The value/default is not -1, but rather 0.
Slightly different behavior between -1 and 0.
LV8.2-LV12 (at least)
