Achim,

I'm guessing that you are using MMSIM6.1. I tried 6.0_USR2 and it works as expected. In 6.1, it appears to only print a message for the error condition. However if I save the output to a logfile, using +log or =log, it does print the messages for the warning and notice to the logfile. There seems to be a problem with the message handler. For the moment, save the output to the logfile and you can continue.

Regards,
 John
