Probe tool not working/corrupted VI?

[BlueTwo]

OK, may be missing something here but...

I have a very simple subVI that i call on several occasions and is used in several projects. The subVI is a couple of years old, and has worked well.

Now the SubVI appears not to run. But it does not show any errors.

If i open the block diagram i cannot use the 'probe' or 'stop point' tools, if i click, they will not put a probe on a wire etc.

If i cut and paste the BD to a new, blank VI i can use the tools on the new VI.

I am about to assume this means the original VI is corrupted...?

XP, full SPs Updates etc

LV 10.1 -current

I think your VI has "Allow debugging" set to false. You'll find this option in the VI properties > Execution.

Or it is re-entrant and LV does not which instance you are looking at.

Thanks for the sugestions.

dan_u,

Yes indeed... i should have spotted it. This solved the probe problem. 

Ben,

The subVI is re-entrant i tried the instance on the caller VI BD, and the 'master' via the Project Explorer window.

I could not get to the bottom of why the subVI did not run correctly. A restart solved the problem, which i guess i should have tried earlier.

I have seen a bug in LV RT :: when probing arrays in a VI running under RT, the probes where empty (if arrays) or bogus.

I reported it to NI and they said the work-around was to reboot the RT machine.

Somehow I disabled the debugger function. I was having a hard time. Your message was the answer. Thanks for posting the answer.

Enable the Allow Debugging check box in VI Properties,for the probe tool to work
