what? no source code?!
oh, a mouse over sensor, nice idea
[I’d probably do an always sensor inverted with no pulses linked to an and controller and a mouse move sensor [again, no pulses, but not inverted] to work around the mouse being reported as moving on the first frame. However, after trying this doesn’t appear to work [because an inverted sensor would send pulses when a non-inverted one would not?]
It admitedly could be a lot more user friendly if it stored the setting in the registry [… or the .ini file] and allowed the user to chose the blender executable run [perhaps copying it into the windows directory renamed], and I guess defaulting to a sdl blank screen [or bouncing box or whatever] if no .dat file found where expected.
