I was sad when I found out the hard way that some of the functions on my HP
R707 did not work when the humidity and heat were high.

I then read the manual and here it was "the camera was made and designed to
operate at 85 % relative humidity and 85 F temperature.

I wonder if it is HP that is not producing a decent digital camera or is it
normal to experience this problem when on a sailboat on a hot and humid
day?.
