Cannot place custom subVI on the block diagram

[David_R._Asher]

When I press the "Select a VI..." button on the function palette and select the VI I want to place on the block diagram nothing happens. This only seems to be happening for two particular VIs. Most of the time I can place the custom subVI without any problems.

Is there some option that could have accidentally gotten set that does not allow a VI to be placed on another VIs block diagram?

Please let me know if there is any way to fix this problem.


Thank you,

I've never seen that one before.

Can you open the VIs in question by themselves?
Can you post the VIs so we can try?

I can still open the VI. I just can't place it on a block diagram.

Attached is one of the VIs in question.

David,

What you sent me has a .ctl file extension. The ctl extension is for LabVIEW custom Controls, not VIs. Even though it is actually a VI, the wrong extension must be confusing LabVIEW and not letting it load. It's probably trying to put it on the front panel since that is where controls go.

If you change the ctl extension to vi, it works as it should.

Wow, I don't know how that happened.

Thanks for your help.
