I would just like to point out that it *was* a problem in Windoze, and
is *not* a problem in Ubuntu.  One *wants* names/words to be case 
sensitive; that's why we have cases!

If you are used to an OS that does things wrong, then it takes a while 
to adjust to one that does things right, but doing it right is still the 
right thing to do.
