yea you should open a second terminal and type
ps -ef | grep $LOGNAME
which would list all the processes on the system and then only print out the ones that belong to you
now you need to find the PID of the process you want to kill (note, pid is the 4th column from the left since the grep will remove the column headings); make sure you pay attention to your terminal as well (you can check which one you are on by typing tty)
and type kill PID
where pid is a number
and this will kill the app process on your other terminal that is "frozen"
