i have just got the demo and am loving it but if i go to F2 view after my plane is wrecked i see a strange thingh where the game stutters textures and the plane is all lines and if i try to quit the quit box is all screwed up.

My computer specs are
AMD 64bit 2.2ghz processer
ASUS in conjunction with niviida grphichs card with 256mb onboard
1.5gb ram
windows xp sp2
all the latest driversfor everything including mouse and keyboard!

F2 view is aircraft external view. If you are doing this after your plane has crashed and there are no other planes in the mission (ie the A-10 mission) it may well be a problem in the demo, it is trying to show you a plane external, but there are no planes to show so it goes @#$%^&.

This may not mean that you will have a problem with the full Lockon. I assume everything else is OK??

i probably didnt make it clear what i meant by when my plane is wrecked i mean when its still flying but has lost a wing or both and is on fire!

You are fine. Mine did that too, but they seemed to have fixed it in the full version.
