Hi guys, I've got a couple of questions I'd like to ask, hope you can answer them 

Okay firstly, does anyone know why the 1), 2), 3) etc choices in the ATC screen seem to randomly disappear in my flights (happens once in a blue moon..)? I have to press the comm1 switch button in the radio stack to get them back. Also, why does my 738 panel always seem to randomly load/lag or "flick" when I toggle with the AP buttons?

Secondly, why do AI aircraft (not talking about MS defaults, I'm talking about Traffic 2005 + WOI) turn black from a distance?

Thirdly  does anyone know why my panel disappears and turns half the screen black (where the panel would be) at EBBR? I haven't tried it at other airports but it seems to happen there frequently. It was with the 738 panel in an addon aircraft, a POSKY 752. I tested with a few others and it happens too..

And lastly, I have really good specs (E6700, 7950GX2, 2GB DDR2 RAM) and addon aircraft with a lot of coloured texture on them seem to load from the model colour (greyish) to their livery colour (looks horrible in videos) when I switch from cockpit to outside view after a long time. It's fine after I repeatedly switch back and forth, but lets say after a minute, it has to load again. Is this a memory problem or does everyone get this, does it depend on the texture size (Would it be possible to convert and get better results)?

Thanks.
