Mine seems to have died, not sure if it has a reset button, but nothing obvious, the problem seems to be with the battery compartment, sometimes it will work, then it'll just crash and go quiet! Removing and reinserting the batteries can bring this about, but like I said, it doesn't work for long, and just now, I can't get it to work at all! Is the Colorino still considered one of the best of it's kind, or has it now been superseded? I need something better than the Cobalt one that thought everything was olive Green! Feedback very welcome - ?Andy
