Wow, Rox. The camera on that is /really/ glitchy in windowed mode. Other than that, cool racetrack. I might have to go check that Quest3D thing out.
Heh, yeah. Quest is INSANELY unpredictable. For me, the camera glitches out when I'm in the editor, OR when in fullscreen mode, but it's incredibly smooth and wonderful in windowed. I think it's mostly my fault, because we've only been using Q3D for a couple of weeks at school, so we have a TON to learn about how the program works.
The car physics took many many weeks to get right... There are so many things to change, it takes forever before you start finding balanced combinations.
About hearing things before sleeping... I do all the time. And it really ticks me off sometimes. If I happen to turn off my computer before going to bed, I can still hear a very strong, high-pitched buzzing (I presume to cancel out the computer's noise, much like eyes try to balance out strong colors) for many minutes after. I also currently keep hearing some sort of really really faint beeping noise, but only if I keep my head in a very specific angle on the pillow... and only with one ear, in that specific angle. It's annoying. Especially when I once decided it's just my mind making the sound up, so I tried to think about something else as best as I could, occationally testing myself by thinking about the noise briefly, and when I did I could hear it again. So it seemed fairly obvious I was just making it up, and so I began trying to sleep again.
And then it started again. And to test it out, I tried focusing on it the same way I did before.. and the sound I had been making in my mind was of a totally different pitch. That really bothered me!
Also, for a period of time when I was younger, I could do SOMETHING, no clue what, to make huge, green clouds float around before my eyes when I was trying to sleep. No physical interaction involved, I would just lie on my back and gently close my eyes and relax, and in a little while my field of vision would fill up with green disturbingness. If it was dark in the room, I could still see it when opening my eyes. I seem to recall being somewhat uneasy from the green showing up totally by itself just before I was about to sleep a couple of times, and keeping me awake for a few more minutes.
After a while, not more than a year I'm sure, it went away.
