it just reels off shot after shot so long as I keep the shutter release button depressed. It doesn't happen on any other settings other than the beach/snow scene preset mode. Although I know how to change the shooting mode, the option for single shots isn't available at all on the menu - it's just "greyed out" so I can't select it.
Regarding the focus light, although the AF confirmation mark doesn't light up as normal, it does appear to be focussing, and gives me a cute little bleep to tell me when it's ready!
