I bought onew of these from Tweeter because I like the idea of a touchscreen with the hardbutton cursor. It regularly locks up, it's forgotten all it's codes once and had to be re-loaded from the computer and now tha touchscreen seems to have gone out of calibration so badly that I can't even get into setup mode to try and fix it. I've read on remote central that there are no end of problems. Even poeple who say they were happy say that it lasted a whole year before breaking. Is this remote just a load of old rubish?
