Hello mrbean,
I'm not quite sure if this is the discussion forum you saw, but the
disable context help discusses a similar issue. This is something you can setup programmatically LabVIEW and it also discusses how to remove the crtl-H/h situation as well.
Another way to address this situation would be to: File>> VI Properties>> Window Appearrance>> Change to Top Level Application Window. Click Ok, now when you run the VI the Context Help Box goes away on the front panel.
