Can't Reach Notice

[s_linkletter]

I have a fully set up display that I have temporarily moved into the staff-only area of the museum, and the game tells me once a minute that "a few people" (namely all the guests) cannot reach this display. The notice is large and blocks my view, and is rapidly using up my patience at the rate of one display per minute. Is there anyway for me to tell the program that I am A) aware of this, B) intended it, and C) to shut up about it?

Edit: I accidentally found the solution. School children were arriving so I blocked it off completely (because of the staff-only door bug with school children) and the message stopped. Apparently it is an emergency if only staff can access a display, but not if no one at all can access it. Strange, but useful.
