Unrealistic circle of rain surrounding aircraft

When I'm sitting on the ground in light airplane (in FS2004) during raining conditions I can see very unrealistic circle of rain surrounding my airplane. I looks like a giant umbrella (about 40ft in diameter) was put above my plane - rain droplets aren't falling inside this circle. When I switch to spot view - the "umbrella" is still over my simulated eye (not over aircraft).During flight when droplets aren't falling vertically but rather close to horizontally (because of aircraft motion) I can see a distint circle without rain in front of me.I think that rain animation in FS2004 done by putting rain droplets on the surface of a cyllinder but this look very unrealistic sometimes especially when the diameter of this cyllinder is too big. Do any of you experience this problem?My setup:Athlon 2000+, 512 MB RAN, Ti4200 (128MB RAM)Display settings (weather):sight distance 60micloud draw distance 40mi3-d clouds 100% (I'm using Chris Willis replacement clouds textures)detailed cloudscloud coverage density max
