I've installed on my XDA Orbit WM6.1 and the 809 Build from RunGPS in German.
RunGPS starts normal, fast GPS fix, but if switching to Navigator or Mapwindows
i have to wait about 2 minutes then i can see the Map for a second and then waiting again 2 minutes.
I thing it is the refresh of the map if GPS koordinates changes.
So RunGPS is useless 4 me.
