UFO's ?????????????????

[G.M.Gratti]

I have the latest G2 with USB Interlink. Latest Direct X, AMD 2400 XP, and all the good stuff. I still get illegal operation messages (no other software gives this message and I mean none). It does run however. Problem is when flying heli about 100feet above ground or higher, some strange object dives at the heli and upsets it. What is this and how do I get rid of it? I think all settings that deal with collisions, etc have been disabled. Can anyone provide an answer and a solution?

Thanks for the help -- Mike
