I'm not really too worried about this, but am wondering whether anybody else has experienced it. When I change from 2D to 3D view in my Piper Archer III, I have to go through the complete cycle of views twice since the first time it goes into the 3D view, the image comes up like a line drawing - difficult to describe, but you just see the shapes in the cockpit (eg. the prop is a filled-in grey circle). Second time round everything's fine. I think its a video card issue, and is just a nuisance more than anything else - but it's only apparent with the Archer III (which I'm now enjoying flying by the way).
