And whilst that can take a while to load (especially if there are a lot of features), it could perhaps be sped up by not actually drawing the shapes on the map (ie just defining the clickable areas). We might still be a while away from this, but with continual improvements to javascript handling/speed in browsers (witness Firefox 3.5, Chrome, Safari, etc) - I reckon it should be possible at some point in the future. You could also start by just doing node-based POIs, which would probably cut down the complexity. Frankie -- Frankie Roberto Experience Designer, Rattle 0114 2706977 http://www.rattlecentral.com
