i'm having a similar problem with polygons with ModifyFeature activated over a simple google layer i would like to drag the map even if the mouse is over a polygon
Is there a way to distinguish between "click and drag" and "simple click" over polygon?? ...something like make the polygon pass the "click and drag" event to the map... thanks -Vito- -- ----------- Tafuni Vito v...@vitotafuni.com --------------------------------------------- "Verba volant, scripta manent... data corrupted" 2010/6/8 Brad Spencer <bradspen...@ozemail.com.au> > Stuart, > > I think its horses for courses really.
