Hello Bruce,
We've run across this problem occasionally in the past, and there are a
few options available to you, in order of usefulness and scope.
First, as you implied, you can exclude all VI's in vi.lib, so moving a
protected VI to this folder will allow for its exclusion without
additional steps. Second, if you are searching the same set of
VI's all of the time, you can search only selected VI's loaded in
memory, manually excluding those that have protected diagrams.
Lastly, you can choose the 'More Options' button and deselect searching
on block diagrams. This will limit your search scope, but will
also prevent the annoying dialog box. If none of these options
are sufficient, I encourage you to tell our developers that this
feature would benefit you on our
product feedback page.
Cheers,
Matt Pollock
