I tried as you said and zoomed in and out. The tool bar is on the bottom locked in place. I've tried several thousand feet altitude, 5000 ft. 10000 ft. etc., etc. It's still bright green. I did down load the latest free version about 2 weeks back thinking that might be it. Still no go. It could be that the latest needs a newer graphic card my PC doesn't have. I can get by with MS Virtual Earth and my map source Topo map software for general research and downloading to my GPS.
It ultimately comes down to doing the research possible beforehand then putting boots on the ground in the most likely areas where there is sign of game and start hiking and glassing to find them..
