Hi! I've just bought a E-PL2 camara and I'm really strugling to get the flash to work I wonder what I'm doing wrong.. - If I set it to automatic mode and auto flash it doesn't work in most cases, let alone if the room is too dark. - If I use M or S mode and flash on all the time, it works whenever it feels like and I don't seem to find out why it doesn't flash most of the time. Please help!!!
