How to workaround a hanging situation when run an Oracle APEX saved report

The problem seems to be impossible, at first sight. As a regular user you cannot do anything but wait.
Log on as developer or admin OF THE WORKSPACE WHERE THE REPORT BELONGS. Go to:

Home>>Administration>>Manage Service>>Interactive Report Settings (link on the right of the page) >>Saved Reports

 select the desired saved report and click <delete>. Unfortunately, there is no other way to stop the hung report. Of course, maybe it will need to rebuild the report, but, anyway, it was designed in a poorly fashion, since is not finishing the run and displaying some data.
