Pentax Optio S4i 1.01

Changes:
Corrected a shutter lock-up problem in certain situations requiring a power reset.
When the camera is set to or used in Movie mode, then the Quick button is used to return the camera to Green mode, some Optio S4i cameras will experience a non-fatal shutter lock-up.
Data record speed in Night Scene mode improved from approximately 7 seconds to 3.5 seconds.
In Movie mode, optical zoom is possible before starting the recording. During the movie recording, only digital zoom will be possible. However, before the recording begins, you may optically zoom to the desired focal length.
