Randomly turn phidgets off. Sometime every hour one time

[cuevision]

Hi

I use Phidgets into my 737 Cockpit as auto shutoff during engine start. Phidgets is turning the solenoid on and off using the Prosim737 software. I do not use it for other functions.

I have had this error in the past too, but today it stopped working twice.

This is what the popup says:

Phidget Control Panel Fatal Exeption (Red Cross):
Unexpected Exeption, Exiting:
Object reference not set to an instance of an object.
at phidget21Manager.Form1.removeRemoteDevice(String[]data)
at phidget21Manager.Form1.remoteMan_Detach(Object sender, DetachEventArgs e)

Hope there will be anyone knowing what goes wrong. You understand that id this happen during a 8 hour flight and the system will fail because of this.....

Thanks to you all and best regards,
Ed
