"Filter in Real Time" option not remembered between sessions

I have the filter on my toolbar. I would like the "Filter in Real Time" option to be selected permanently. However, when I close or exit Opus this option is unchecked.

Is there a way to keep this option selected permanently?

Thanks,

Harrie.

That did it again, thank you.
