Vista - Difficulty when Moving Messages to folders (WLM)

I find that when I want to drag a message into a folder it is a bit difficult
to see the folder....ie. although it becomes boxed in a colour....the colour
intensity is quite light and difficult to see. Is there some way to brighten
up or highlight the folder which you are dragging to, so that you can be sure
that you are dropping the message in the right folder and not the one above
or below. In my case the folder does change to a light blue colour but it is
not really very bright.
