To me it looks like an overoptimized geometry problem. As long there is 
only sky and no terrain or building behind the objects, you can klick 
them. This is mostly the case, when you look up. Just like users reported.

I just wrote a lousy mmap wrapper which sets start to 0x10000000 . This 
works for me with wine 20050601 and the latest from cvs.

Latest cvs raises another bug. When the wow window looses focus, it 
minimize and maximizes again and stays on top. More worse, the graphics 
is shifted to approx. +2+2 pixels every time. Here's the output from 

fixme:opengl:wglQueryPbufferARB unsupported WGL_PBUFFER_LOST_ARB (need 
glXSelectEvent/GLX_DAMAGED work)

... and the TODO becomes a bit longer again.
