Some issues with FSX?

Hi,I have tested out the beta of FSX for a while now, and I have noticed a couple of minor things that might be a bug.I have noticed that when I'm flying a single engine cessna in wet weather, the water is being blown backwards behind the propeller when full throttle is applied. However, when I'm changing to a 747-400, the water still blows backwards right underneath the aircraft. It looks like FSX still think I am flying a Cessna. The water shold be blown back behind the four engines.When I fly the 737-800 and come up to about 7000 or 8000 feet, the autogen objects start to disappear in squares. I have all settings set to high, except the water. I don't know if this is a bug or if it is meant to be like that, though. Are we suppose to see autogen objects in FL200? or FL350 for that matter?As I said, this is just a couple of minor things I wanted to get off my chest. I don't know if they can qualify as bugs, but now I at least have listed them.I'm looking forward to the release which shoulb be just around the corner now :-) RaymondNorway
