BsxCuBE is frozen, disappears, some information are grey or it is not behaving as expected ??? 

- first kill it properly: with its killing icon, or tape "ps aux | grep BsxCuBE" and "kill its_PID" in a X-term window on nela

- restart BsxCuBE: with click on its icon or write "BsxCuBE" in a X-term window

- if still problems, stop BsxCuBE and restart the COServer and restart BsxCuBE
