having a myriad of problems with 2004

I have a few problems. maybe you can help. First of all, the trees poorly shaped... look like two pieces of cardboard placed like an "x" through eachother...

Also, the ATC screen is blue, not a nice see through color like in 2002.

The game is running EXTREMELY slow... like when I close the GPS...there is a good delay. my system is 800Mhz. Dont' think that's the problem.

The puffs of smoke, so realistic in 2002, are now just rectangles shooting off from under the wheel.

I have problems with earlier aircraft flow affecting current aircraft... for instance... i flew the wright flyer first... then flew the new DC3...and the DC3 steered like the wright flyer... maybe a bit better.

on the DC and the FORD, the wheel that steers is not moving. I have to use the brakes to steer.

Probably the most problematic for me, because it actually has made me crash once is when I am looking externally at the plane, There are a series of black rectangles starting small next to my plane and resing to the sun.. so large that the southwest corner of the world is BLACK... and No, it's not getting darker as in the sun is going down... there is litterally a huge black rectangles in the sky. If I fly out of meigs, take a right and head back into the airport, I the whole screen goes black as I face these black triangles of death. lol.

Any ideas?? anyone??

LIike I said.. I'm running 128 mb of ram, 800 Mhz. pentium III well beyound the system reqs. my video card is a SB 4.0.

Is anyone else having ANY of these problems?????

Thanks
