I'm using 4.5.1, and now for one reason or another the host settings config doesn't update at all after making any changes.  This problem started occuring after I checked off the whitespace filter, and added a whitespace regex.  There are no errors in the events logs.  It's very strange... Is there any manual way of making the changes without using the gui?

I fixed it... I did have to go into the table and changed the settings back manually.  After doing that and restarting it, it seems to be working now.  Won't do that again.
