Finder does not update
I've heard of this happening before, but can't put my hands on a link right now.

Try this applescript, save it as an App
It refreshes the contents of all open Finder windows by switching them to another view then back again.

tell application "Finder"
    set theWindows to every window
    repeat with i from 1 to number of items in theWindows
        set this_item to item i of theWindows
        set theView to current view of this_item
        if theView is list view then
            set current view of this_item to icon view
        else
            set current view of this_item to list view          
        end if
        set current view of this_item to theView
    end repeat
end tell
