What operating system?

If you're on Vista, instal VistaBoost and I believe it might help to disable that transparent sidebar.

VistaBoost solved the problem on my dad's laptop with Vista...

I also had extremely odd problems with Chinese characters popping up in a debug string when I ran Orbiter on XP. I really had no idea what it was, but it may very well have been a problem with the actual machine. What kind of computer are you using?

like the characters in my picture is just not chinese,i don't know what's that.
