I took 100+ pics a week ago - all worked fine - all pics on card xferred to PC OK. Today I took another 20 fotos - all showed up OK when viewed on camera's LCD. When camera was turned off, then back on, the pics were gone! When card xferred to PC only original 100+ were on card. Resetting camera to defaults seems to have fixed problem (or has it?). What happened? Don't want repeat. Hint: clumsy person played with camera between two picture sessions. Thx, tiredviking@netscape.net
