I'm sorry this may be a little off-topic, but I'm getting desperate!
I have a device which uses a SAW touch screen. I have a problem with how it reacts to touch. If I press in one spot and then press in another the initial "click" is released and the device reacts to the new click. I need it to freeze until the initial click is released, ignoring any other touch. Is there anyway to do this? Any hint (involving any platform, OS, driver, application) would be greatly appreciated.
