Exuse me, but it works on my computer :) And thanks about this topic, I 
didn't know about this feature!

I selected region by Ctrl-v, pressed Shift-I and white selection 
disappeared, I pressed # and ESC and got this effect...
My vimrc:

" You can override any of these settings on a global basis via the

" The following are some sensible defaults for Vim for most users.
" We attempt to change as little as possible from Vim's defaults,
" deviating only where it makes sense

set bs=2                " Allow backspacing over everything in insert mode
set ai                  " Always set auto-indenting on

set ruler               " Show the cursor position all the time

" Don't use Ex mode, use Q for formatting
map Q gq

" When doing tab completion, give the following files lower priority. 
You may
" wish to set 'wildignore' to completely ignore files, and 'wildmenu' to 
enable
" enhanced tab completion. These can be done in the user vimrc file.
set suffixes+=.info,.aux,.log,.dvi,.bbl,.out,.o,.lo

" When displaying line numbers, don't use an annoyingly wide number 
column. This
