That stinks. I'm not sure what else to suggest. At least you have a workaround (-3 EC) until you either find another poster who can dig deeper, or get it to Canon. I just looked through the manual to see if there was some sort of setting that could set a baseline EC or something, and found nothing.
Please post back whatever you learn.
Thanks for your help! I've posted a thread and quoted some posts in it, will see what happens.
