When racing, the sky is black. An OpenGL bug perhaps? Weirdly when it's
showing the pre-recorded demos the sky is just fine. The rest of the
graphics are perfect.

What graphics card and driver do you use?  This is important.  I use a
Radeon 9200 and DRI.  In Warcraft III+opengl under wine,  things would
"disappear", but then re-appear under different conditions. I have
screen shots I can upload that shows this in action.  I used to use an
nvidia card with the official driver.  Comparatively, the nvidia
graphics setup rendered everything perfectly.

Finally if you put it in desktop mode, an X protocol error occurs
initialising OpenGL. The XGetWindowAttributes call complains of a bad
window. I debugged this for a bit and got nowhere, it wasn't as
straightforward as it looked. Suffice to say that at the point it died
opengl32.dll had been initialised several times already with the same
value for root_window, and it worked each time previously (yes sync was
enabled).
I think this definitely used to work, so it feels like some WM rewrite
regression to me. I could well be wrong though.
This seems to affect all OpenGL+desktop mode apps.
You are correct, it used to work.  I just tried it yesterday and it
didn't work for me either.

To make the game let you choose OpenGL in the setup program it has to be
run in win2k/winxp mode. I do not know why.
If you get it going, see if you can beat my best time (when playing on
Linux) of 2:02. Have fun! :)
thanks -mike
Unfortunately I can't try your game at the moment cause it will take
me too long to download -- 2 KB/s down only =(
