Canon has released 1D Mk2 and 1Ds Mk2 firmware updates. I thought these problems were fixed in the previous firmware release, but I guess they weren't.
1D Mk2: [download]
This firmware update (version 1.2.3) includes the following improvements:
* With the version 1.2.2 firmware, pressing the DISPLAY button right after shooting images resulted in an abnormal display and the camera would freeze. This firmware fixes that problem.
This firmware update applies to cameras with firmware version up to 1.2.2 installed. If your camera's firmware is already version 1.2.3, it is not necessary to perform this update.
1Ds Mk2: [download]
This firmware update (version 1.1.3) includes the following improvements:
* With the version 1.1.2 firmware, pressing the DISPLAY button right after shooting images resulted in an abnormal display and the camera would freeze. This firmware fixes that problem.
