I read about the head/tail files but wasn't sure what they did or how it 
worked.  I need new glasses so I can see better.  I spend more time 
trying to read than being able to understand what I read.  -_- <<==  
That would be eyes closed.

I guess I could have created a head file and just put my prefs on top.  
Thing is, I just removed the overlays so now I don't even need this.  
lol  Then again, those are faster than my ISPs servers.  Still better off.

Thanks for the info.  I learned something.
