[Wien] x nn invalid null command.

[Vit]

Dear Wien2k users,
We are new to using wien and now on fresh wien install we have some problems.

After folowing manual on page 24 and starting x nn here is the line (Invalid null command.), which is realy confusing.
Here is the output:

Commandline: x nn
Program input is: "2 "

Invalid null command.
STOP NN ENDS

  At the same time there is nothing wrong in :log.
Could you please help we to find this error?
With best regards,
Koroteev Victor.
