While working in studio with all the flash units and my Canon 40D top with a radio trigger on the hot shoes, one of the flash have the receiver. It work very well with the camera (I was shooting manual set at "M"), when I shoot live view, the trigger can not sync with the flash unit, if go back to normal shot, it sync and fire every single flashing.
Like to let Canon people know about this "bug" here, hope thy can improve on the upcoming firmware update.
Cheers
Paul
