Hello,
i just found this bus on sql developer while creating a scheduler job with the type chain.
When i create such a job that runs some chained programs, i see this job 2 or 3 times duplicated under the "Jobs" folder on the treeview:
(all the JOB_C are jobs based on chains, and they are duplicated here:)

I'm using the last version: Version 4.1.3.20 Build MAIN-20.78 on windows 7
Can you please fix this?
Thank you
Best regards,
Joao
