problem with new bb 9780 gps

google maps and blackberry maps doesn't work like it did on the 9700. ive read some of the other post and dont see an answer. it will show where i am at and my arrow will move off the page instead of the whole map tracking down as i move if i have zoomed in to see all the streets. also with telenav that is the best so far of all the maps i have tried. but just like google maps, blackberry maps, and telenav if i havent clicked on the app it wont refresh the sat unless i do a batt pull or alt right shift delete to reboot it then it works fine. well u shouldnt have to do that for it to pick up a sat. the 9700 didnt have these problems. does anyone know of an update that will fix this problem.
