I just learned that Canon made a few tweaks in the firmware for the EOS 7D.
Firmware version 2.0.3 incorporates the following fixes.
Fixes a phenomenon in which the camera stops working when the auto power off setting takes effect.
Fixes a phenomenon in which the maximum number of images that can be captured in a burst may be less than the actual number displayed in the viewfinder.
Corrects some errors in the message displayed on the LCD screen when saving RAW images developed in the camera (these errors do not appear in the Japanese and Korean language displays).
You can get the firmware and instructions on how to update your EOS 7D, here.
