Well this made an perfect example that Murphy really exists. As soon as I
made my first post I got hold of a friend that solved my problem.
He showed med the solution ...
m_directinput [0/1]
Enable DirectInput mouse support. Use in_restart to restart the input sybsystem after changing this cvar
I may say that it was not obvious that this cvar made the difference. I am no
high tech pro so I missed that completely.
Sorry for bothering and taking up some binary space
