SW2011 redundant vertical or horzontal restraints

I just updated from SW2010 to SW2011. I find that a redundant vertical or horzontal restraint will cause an "over defined" error. I don't think this was the case in SW2010, but maybe it's smethign in this particular skecth. Was this channge? Is there a setting?

Thanks
