RAF_Doumilan,
I have no clue about #2, except that others may need to know more about your computer and graphics card to help troubleshoot.
and as for #1,
I believe that you are saying that the airplane moves with the Throttle at 0 . Having flown real-life King-Air 200's, 100's, and 90's, I could tell ya that if the powerlevers are at idle....the airplane WILL move unless the brake is set or the aircraft is chocked. I do not know if their is a patch/fix to overcome this in the game, but in realife...it's a fact.
This is mainly due to the props being at High Pitch during ground idle....it creates quite a bit of thrust (enough to overcome the weight of the aircraft) and propel it foward....this is why many pilots will taxi a King Air with the props set at HIGH PITCH but the Powerlevers in the BETA range. Beta Range is the area between Low Pitch and Reverse. This range produces less thrust...to...reverse thrust and allows for easier taxing...even to the point of turning using differential power (prop pitch).
I haven't flown the King Air in FS2004...I mainly stick with the Lear 45 since I'm more familiar with the Lears, Glass cockpits, and equipment location in general.
I hope some of this answers some questions......
