Did SP4 break configurations?

Is anyone else noticing that SP4 did some very evil things to configurations?  Basically they don't work at all.  No matter what I do there is no way around the giant bug.  It's almost as if nothing is in synchronicity.  I've tried using only design tables and blocking model edits but this doesn't work either.  It seems the only thing functioning correctly is a direct model edit with the configuration set to "this".SolidworksConfigurations design Tables
