Casio EX-S12

[[email protected]]

I purchased a Casio EX-S12 recently. I had an older Casio EX7 something previously and for the most part operating the new one has been simple. One thing I can not figure out. When I take a picture there is a 3-6 second lag where the screen goes blank and states "Busy....Please Wait..." after every picture that I take. I can't figure out what set up needs changing to stop that or is it something I will have to get use to? / Thanks in advance.
