While attempting to view survey points for deterimining density of topo shots I find that all points now are missing from view although am able to stake to individual points and then that one point appears and stays put until a different point is staked which replaces last one. Rebooted, zoomed out, zoomed in.....nothing. There is a shape file in place which I suspect is at the bottom of this problem. Any similar experiences?. ......resolution? Thanks. Mike Magoon
