Thanks for looking at this.  I'm not opposed to reverting the generic 
entry stuff if it's breaking things, but it's a nice cleanup so it'd be 
great to keep it if possible.  I'm going to keep picking up other 
features for now, but if folks run out of patience trying to fix the bug 
then LMK and I'll figure out how to drop the series.
