Probe always dimmed when right click on wire

[NJMRFID]

Hello all, relatively new Labview user here!

I am working with Labview 7.1 with a functioning vi developed by someone else here. They're no longer w/ the company and I'm the point man.

This vi gathers data over a TCP/IP connection to a device connected via Ethernet. It is the only device on the PC's Ethernet adapter. As previously mentioned this vi is known to work.

My question is this... when right clicking on any wire in the vi, "Probe" is always dimmed so that it can't be selected. This is the case whether or not the vi is running. Can anyone give some insight into why this is?

Thanks,

Ron

Debug is not enabled for the VI or it is marked as reentrant. If you go to File>VI Properties or right click on the VI's icon and select VI Properties, go to the Execution category. Reentrant execution is a checkbox over on the left side and Allow Debugging is on the right.

Thank you, works like a charm!
