You know, I had read that two weeks ago and had a feeling of deja vu 
when I actally ran into the problem last night, but for some reason 
didn't remember nor go back to check the obvious place.  Why is it 
that Release Notes don't seem to apply to your situation until you 
actually hit the problem?  Oh well.

Anyway, becase this is in the Limitations section, not the Outstanding 
Issues section, does that mean it won't/can't be fixed?
