Your debug script probably has a invalid pl/sql code.
See my post - http://www.allroundautomations.com/ubb/ultimatebb.php?ubb=get_topic;f=3;t=005346
if in test script write some invalid pl/sql code
i.e.
DBMS_OUTPUT.put_line( to_char(rec.ode_kz, ' 000' ) );
( error ' 000', right '000' )
test script and pl/sql developer environment is hang up.
One way stop its - kill its from task manager.
