Weird graphics...

Hello. I'm new to FS2004 and I am having some graphical errors. Whenever I'm at an airport at night, the runway is dark, but most of the taxiway is bright, like its in daytime. Can anyone help?

My system:
eMachines AMD AhtlonXP C2280
Processor: AthlonXP 2200+, MMX, 3DNow, ~1.8GHz
RAM: 224 MB (The supposedly 256 MB it says on the box)
Video Card: S3 Graphics ProSavage DDR
BIOS: Phoenix-AwardBIOS v6.00PG
DirectX 9
About 10 gigs of memory left out of about 74 total gigs.

Hi guest, try hitting the "L" key as it sounds like you have landing lights on. Good Luck, rob

I am having the same problem, but it present itself whenever I select weather, the runway doesnt appear, and the ground graphics blocks the airplane on the spot view. By the way, your system DOES have 256mb of memory, the thing is that you're sharing 32mb for your onboard graphics S3 Prosavage DDR card, if you add it up, you would have 256mb.
