Would an error message like the following help?
Error 1193 occurred at ...
Possible reason(s):
LabVIEW: When a Boolean control has a latch
mechanical action, you cannot use the Value
property to read or write its value.
This error message should get people unstuck. For the curious at heart, wondering why this is so, they could then go to help and find the following under "Changing the Mechanical Action of a Boolean Object":
Note: You cannot use any latch action for objects
with a local variable because the first local
variable to read a Boolean control with latch
action would reset its value to the default.
I know - a little late to help you, but those who follow will be a touch less frustrated.

P.S. It was a redundant question - no need to answer. Our support department has made us fully aware of the problems poor error code returns and/or messages can cause, and this specific example was their poster child.
