Wrong Warning Message when switching a clone to Edit mode?

[X.]

I was surprised to see that when trying to switch to the source VI of a clone with the Ctrl-M shortcut, I got the following warning:

Nothing in that message makes any sense, as the clone was idle, and not used in the other project opened in that LV session.

However, another VI running in another project was using the Uniform White Noise (obs 90).vi, which, deep down, IS a subVI of Pareto Random.vi (and calls a DLL).

That's the only connection I could find, and I don't understand why it should prevent me from switching the Pareto Random.vi to Edit mode.

Is this because it is part of a lvlib?

Hi X,

If you stop the other project that is running the Uniform White Noise do you still get the error? If so when you restart your computer and run just the one LabVIEW project do you still get any errors? Also are you able to reproduce this error?
