I have a lilliiput 7'' in dash touch screen. The monitors works fine but I have a problem with a sound when touching the panel. THe sound can not be turned off, I have tried advanced settings but it seems that it is not working, can not even change the pitch or anything, when I uncheck sound or it is checked there is no difference. For me it sounds like a software lilliput problem..any ideas? how to turn this off?

thanks
