Hi John and Torino,
"Try creating a new session to see if the commands are available. "
I did that and there were no problems , stupid of me not to try that or take an other excisting route.
I checked CM  for anything faulty  and the default session was gone . 
All that after a forced closing .
But when CM is freezing , do i have to wait , maybe one hour that CM comes alive again ?
And Torino , i have now about 60 items with missing dependencies . 
Thank you both for the attention.
