hilight destiny folder in nautilus

[nor <nor this-dimension com>]

Hi, I'm new to linux and i'm not even shure if this is the right place 
to ask for on this one...

This is my problem: When i'm using nautilus in tree view, if i drag a 
folder or a file to the tree on the left, i can't hilight the destiny 
folder. How can this be made? By changing the gtkrc of the gtk theme? By 
changing some icon or image?

Sorry, I gess this is too boring for you but can you help or give some 
orientation?

Thanks in advance, Nor.
