Um, ok, but not exactly, at least on my 5D/580. Testing the same way, it does LOOK like the compensation isn't being changed in the bounce positions. However, if you then press the shutter button 1/2 way, you'll see that the compensation has been changed. It looks like what happens in the bounce positions is that as soon as you press the center button on the 580, it clears the part of the screen that normally displays the amount of compensation. When you press the shutter 1/2 way, the display is restored. Probably has something to do with the way the 580 display flashes on & off in the bounce positions.
