How to stop script warning/Error/Debug from showing at sim crossings?

[ral61 1]

One of my helicopters is now showing a script warning, error, debug message, at every sim crossing flying the plane.

I have to click off each one of the message pop-up, at sim crossing flying. 

Is there a debug section to stop this from happening?

To know something is "amiss", there's planes hanging in the "air" to be concerned about the stability of the viewer.

Clearly, there's something wrong with your GPS script.  It's looking for a texture that isn't there.  Fix that and the error messages will go away. If you don't fix it, the other solution is to turn that script off or remove it.
