When doing the same in Native Oberon (on PC), you can recover by
pressing Ctrl+Break, since Native Oberon's TRAP handler will open a new
log viewer if the log viewer has been closed.

But I just tested it in PO2013, this "safety precaution" is not
implemented there. But probably not hard to add if anyone needs it :-)
