Are you waiting for the buffer to clear?
I upgraded from the S90 to the S110 and love most ot it's features. But the alleged ability to shoot several frames per second (when holding the shutter button down) has only worked occasionally and I can't figure out how to make it work reliably when needed. It took terrific pics when it worked. When it doesn't, the camera only repeats about 1 fps. I selected "continuous shooting" on the menu And the display shows that symbol. But it has a mind of its own!!
Any suggestion or answer?
