Display tooltip when mouse is over a point

[Milo van der Linden]

Your question is all client side related. There are several clients out 
there that you can put on top of Mapserver WMS (and sometimes WFS)

Projects that I think are active and stable are:

- Google Maps: http://code.google.com/apis/maps/
- OpenLayers: http://www.openlayers.org/
- Flamingo MC: http://www.flamingo-mc.org/


Look in to them for details and select your client component of choice.

Kind regards,
