How does the controller know that the display program has failed?

Hello, is there a way the PAC controller (be it a PAC-R1, S2, or any other SNAPs) know when a currently running display program has failed? Thanks.

Check out [U][B]this post[/B][/U] where we had a fun brainstorming session on just this topic, and got a great suggestion from OptoFan PilotMan who even inspired the example and video in post #9 in that thread.

Let us know if you mean something else other than what that discussion meant to solve (e.g. Windows or the PC crashes, connection down, something like that?)

Actually this is what I’m looking for. Thanks!
