Hello I've had a Canon PowerShot A75 digital camera for more than a year now and it recently started to exhibit the following problem: When the camera is in shooting mode it suddenly switches to playback mode not allowing me to take any more pictures and showing me playback options instead (like browsing through the images). To get it back to shooting mode I have to turn it off and on a few times and toggle the switch back and forth between playback and shooting. This is very annoying and is happening all the time. Does anyone knows how to fix this problem?
