buffer name selection not case sensitive

[Mickey Ferguson]

I'm now using emacs 24.3.1 for Windows.  With the old version I was using 
(21.x?), when I went to switch to another buffer (C-x b), I could type the name 
of the buffer in lower case and it would find it even if the buffer name was in 
upper or mixed case.  Now it doesn't find it unless I get the case correct.  Is 
there a way to change it so that the buffer name matching is case insensitive?
