Hybrid and Sleep

When you add/start a job it does this (so clearly Hybrid intentionally blocks sleep which is good):

No it doesn't. Windows blocks the sleep since there are non-local files open in write more. (This is nothing Hybrid does actively.)
Also Hybrid has no control over those files during an encoding as they are controlled by the encoder during the encoding.

Are there any settings relating to "sleep" in Hybrid?

"Job->Misc->On queue finished" can be set to Hibernate.
Other than that: No.

Why is Hybrid blocking sleep when its not doing anything?

No clue, since Hybrid isn't actively doing anything to prevent sleep/shutdown/...

Why has this started now, when I have put the PC in sleep countless times before now?

Since I haven't changed any code that from my point could be related for years, my guess is Windows changed something with a recent update.

Is this expected behavour?

No, but it also was never indented either.

Do I simply need to kill Hybrid when its not in use?

If you want to tell Hybrid to close once it's finished, set "Job->Misc->On queue finished" to 'close'.

Or is there a reason why this is happening?

No clue how Windows decides whether a program prevents it from hibernating.
