One more detail... when I press the normal power button, it always goes to play mode, whether I press long or short. However, when I press the shutter button once the leds blink, the lens extracts and it goes into shooting mode. The programming / settings osd comes up (P, ISO, etc.) and there's movement of some icons. After 2-3secs again, the screen freezes and movement stops (crash?).
Thanks!
