During the executing the a store procedure debug, I need to cancel, I stop debug with break shift+esc then the plsql/developer is frozen until I kill the windows process
I am also facing almost the same as described here. 1) I start on debug mode. 2) I encounter an exception 3) PL/SQL developer is not frozen but no action could be performed. 4) I have to kill the process and re-open again.
