Roborun+ Joystick disconnection defaults to -1000 on both motors

Hi,

I am having problems with the Roborun+ and running a couple of motors with the joystick interface. If I loose connection, Roborun+ automatically defaults to giving -1000 out to both motors! Pretty unsafe... It is not the joystick sending rubbish, that I have checked.

Have any other experienced this? and have you found a solution to fix it?
I know I can just use a spektrum radio instead, but I have a PC on my application and a wireless BT joystick for it. Problem is of course when the joystick disconnects because of running out of battery or inactivity - then things go crazy!
