tooltips

[Justin <Elshadii carolina rr com>]

I would like to add tooltips to desktop icons, how would I go about 
doing this?  and also I would like to add an icon for the removeable 
media icons to my desktop with the same functionality ie changing when 
mounted, as the one's contained within the Computer icon already on the 
desktop.  Could someone please explain how I would go about doing this.

Thanks
Justin
