I just experienced some of what I'll call OS hangs or loops in the CP5400.
The camera powers up normally and when you take a picture the green light flashes like it is writeing to the CF card, 20mins later it is still doing this. During this time most camera functionslike zoom seem to work, but it won't try focusing or let you take another picture.Only way to get it to stop is to take the battery out. Reinsert the battery and it is working normally again.
Suspect maybe a bug in the new 1.4 firmware? Haven't heard anyone mention this issue anywhere yet so maybe it is just my P&S.
:cart:Maybe I'll just use it as a skeg next time it fouls up:angry:.
