Subject: win32-changenotify and modifying a file

    Hey!

I'm working with win32-changenofity library to listen for any changes in 
a directory. I'm interested in added, deleted and modified files. That's 
my code:

#-------
filter = ChangeNotify::FILE_NAME | ChangeNotify::DIR_NAME
abs_path = File.expand_path(dir)
ChangeNotify.new(abs_path, true, filter) do |cn|
   cn.wait do |events|
     events.each do |event|
       puts(event.action, event.file_name)
     end
   end
end
#--------

The problem is when I modify file on disk, it's not reported. When I use 
additional filters like SIZE or LAST_WRITE I get changes reported few 
times. Is there some combination which will report file change only once?
