My 7590 is no better...goes to sleep after 60 seconds. After 8 minutes of no activity, it SHUTS DOWN ! According to Kodak thats how it was designed to save battery life. I've gotten in the habit of hitting the shutter halfway every couple minutes when there may be a quick opportunity for a shot.
I hear you Dan, this has become my trick too. But of course I inevitably forget at some point and still miss that once in a lifetime shot, LOL.
Hey Dan, have you ever been to this forum,http://www.easysharersforum.com/
it is all Kodak related. You should check it out. I've been gradually spending more time at it.
