When using Opera Browser my DS Lite shuts off whenever I flip it back open. It goes into sleep when I close it but when opening it it flashes 2 white screens for a moment just like whenever you wake a DS up, but the next moment instead of displaying whatever was on screen at that time it just shuts down. No other games do this. Yes the battery is full. I'm using the 3in1 and Supercard DS One v3. Suggestions?
