Restart is normally not required after installation of JustCode. Can you please check the following folders on your PC:
(for Windows XP):
C:\Documents and Settings\[Your Username]\Local Settings\Application Data\JustCode\Logs
(for Windows Vista / 7):
and send us the latest modified files from it (i.e. from the date you observed the abnormality)? You can also check the "Logs\NotReportedExceptions" folder and if you find some files there too, please send them to us.
Let us know should you happen to stumble upon that issue again.
