, the camera just "freezes". The LCD shows "fEE" . I have occassionally had the same problem and, in my case, discovered that the flash had shifted just a bit in the shoe and was not making proper contact. Removing the flash and putting it back on solves the problem because by putting the flash back on you usually put it back with the contacts properly aligned. Making sure the flash is tightly attached seems to be the best fix. It it is not firmly attached it seems to like to slip backwards in the shoe causing this type of problem. Dave
