RE: maps
Google Maps supports Windows XP (that is what I am running). You do not need Vista in order to use their maps. There may be routing issues at this time, but you do not have to change OS's just to view the maps.
The Google maps were installed in place of the Map Quest maps because they are more detailed and will allow additional features that could not be used with the old system. One of the features we will incorporate soon with the Google Maps will be show pins on the map where items posted for sale are located. When one of those pins is clicked on, the ad title, description and photo will be displayed along with a link to the RCU ad.
