Sonar message boxes

Hi all
I am using FW 3.2.2 and I have just installed a MaxBotix MB 1240 sonar I also am trying a MB 1260. They seem to be working ok however I am getting some irritating message boxes all the time flashing up on the screen informing me of the range. Does anyone know how to switch them off but still retain sonar functionality. I am also using a upto date version of mission planner.
Regards
Max

Max,

This would be a mission planner issue so perhaps raise an issue with Michael Oborne over here on the MP issues list.
