AFAIK, the radar has only 3 diffrent view angles, and this was corrected with 1.1, and it's fully normal. As for horizontal snapping, could you describe the problem a bit more?
In the bottom of the hud, you have this number, default "10". This is the expected target distance, so you need to set it up according to the EWR/AWACS picture or RWR. Then you need to look to the right of the hud, and move the radar up&down. You'll see the number change. This nubmer represents the altitude the radar is looking at the current distance setting. For example, if you are flying at 5000m, you have set the radar to 50km and the rightmost number is showing -2, then you are scanning 3000m altitude 50km away from you. Of course, the radar will see other distances&altitudes aswell..
Add me to your msn list and i can propably explain a bit better.. you'll propably know where to find the adress:)
