I usually use windows XP for AH but since the hard drive kicked the bucket I've had to go to some other computers to check my work. I was using my grandfathers new computer which runs Windows 7 and I imidiatly noticed some things that seemed off. To start, I couldn't even veiw the skin in the game even though I had downloaded the High res texture pack. I have no clue why it didn't work, but I was assuming it was because there was not skins folder after the initial download. Does that make sense?
The second thing I noticed is that compared to the computer I have now, the skins on planes are exessively "shinny" I don't know if that is just because of a newer graphics driver or not but I'm sure skuzzy would know. I tried taking a screen shot of it but it didn't turn out (shift + Print Screen). I can describe it though, it looked basicaly like a solid white line running along the area of the plane that was exposed to the sun, and you couldn't see any of the details under the line. It was vaugly noticeable on the win XP computer but it was still there.
